IFC and PRO-IFC by Karl A. Hessinger IFC stands for Interactive File Controller and that's just what it does - IFC controls a drive's files interactively! IFC is great for managing the files that collect on a drive. It presents you with a scrollable sorted directory on your video display screen and a collection of operations to tag/untag selected files in the list. With IFC, you can copy, delete, rename, or list files - all interactively and based on your specifications for tagging. The more files you keep, the more you need IFC! Enter IFC and tell it what drive to work with. Something similar to the following display of files will be presented: Drive : 2 Name : TRSDOS61 Free : 6K Tagged : 0K --- --- --- --- ==> BACKUP/CMD:2 10-Feb-84 7K : BASIC/CMD:2 10-Feb-84 22K : BASIC/OV1:2 10-Feb-84 3K : CLICK/FLT:2 10-Feb-84 1K : COMM/CMD:2 10-Feb-84 3K : FORMAT/CMD:2 10-Feb-84 5K : KSM/FLT:2 10-Feb-84 1K : MEMDISK/DCT:2 10-Feb-84 3K : PATCH/CMD:2 10-Feb-84 3K : That '==>' file cursor points to the current file and can be positioned to any file. This 'current' file can then be copied, deleted, listed, or renamed as easily as pressing a key. The IFC-list operation pauses as the listing fulls the display screen. IFCLIST can also be used as a stand-alone program. Any file in the list can be tagged simply by moving the file cursor to point to the file and press the <t>ag command. A mass of files can also be tagged according to attributes such as MODIFIED, INVISIBLE, or PaDS files. Tagging can even be invoked according to an ambiguous file specification commonly known as a WILDCARD. In addition, you can even specify a second disk drive and tag those files that are on both drives thereby providing an OLD/NEW tagging specification. The copy, delete, and rename IFC commands can be invoked on the mass of tagged files. This operation really improves the file maintenance capabilities available at your fingertips.</t> Forget the command nomenclature? Help is available on-line! As easy as typing <ENTER>, [or four other characters to make it easy], IFC gives you: A - Again, retag files C - Copy current file --- --- O - Tag old files D - Delete current file T - Tag current file L - List current file U - Untag current file R - Rename current file W - Wildcard tag/untag +I - Tag by attributes E - Exit to DOS == <M>ass functions == F - Free space on drive C - Copy files H - Display help D - Delete files Q - Execute DOS command R - Rename files S - Select new drive Press any key to continue ORDERING INFORMATION: IFC: For the TRS-80 Models I/III/4 with LDOS 5.1. PRO-IFC: For use with LDOS/TRSDOS Version 6 [i.e. Model 4].

Tutorial on optical illusions.

Published in CLOAD Magazine, June 1980. TRS-80 Level I 4K and Level II 16K, cassette.

IMAGE PROCESSING KIT - HIGH QUALITY REPRODUCTION This program is somewhat different to our normal programs and perhaps we should get the differences out of the way to begin with. An image processing procedure is one in which a camera, the type normally hooked up to a video recorder, takes a picture of a subject. This picture is digitised and after various processes finishes up as a disk file on the computer. By way of a good printer (such as the Epson MX-80 series though ANY printer - dot or not - can be used) this file can be converted back into a picture of the original subject. The quality of the picture, with a good printer, is quite amazing. The quality with a non-graphic orientated printer is reasonable. As can be seen from the above description at least two items of hardware must be purchased in order to construct one's own pictures. Consequently this package is not a complete one in the sense that buying it will enable the customer to go out and take his own pictures ( unless he has the additional hardware). What it is, is a package by which the user can get a very good idea of what will result from a complete set up. Image Processing Kit gives you the opportunity to conduct experiments in image processing without buying expensive hardware. You will, however, be restricted to the images which are supplied with the kit. The kit consists of six different files, each containing an image, already in digital form. There are also simple programs for getting the images on and off the disk as well as displaying them. Sixteen pages of documentation are supplied with the kit describing in detail the working of the program and outlining further experiments that may be performed. The images can be viewed on the VDU if you wish, but the resolution is not so good, so a printer is pretty well mandatory. The kit contains a machine code program to drive the MX-80 Printer so that the final printed image is made up of dots, the compactness of which make up darker or lighter tones. The source code for the MX-80 driver is supplied in the kit and hence it is possible for a reasonably adept programmer to alter it to suit any type of printer. For customers who are not into machine code the same program is also written in Basic. This, of course, takes longer to run, but the result is the same. We would like to once more emphasise that this kit is intended as a starting kit to introduce interested customers to the world of image processing. It is intended as a spring board for the users on experiments and programs. By writing programs to perform the experiments outlined in the documentation the user can gain insight into the type of processes that NASA performs on its deep space pictures. Memory Requirement 32K/DB TRS 80 DISK Model 1

IMON - AN ADVANCED MONITOR You are probably curious why we stock IMON together with MONITORS 3 & 4. The explanation is that the preceding Monitors are designed to be used in conjunction with Basic programmes, or a least with the capability of loading both the Monitor and a fair sized Basic program into memory at the same time. IMON is aimed more at the machine language programmer who only needs 3 or 4k usable memory (in a 16k machine) in addition to the Monitor but who requires additional commands, particularly applicable to machine language programming. In the following list of IMON commands therefore, the emphasis is given to those commands which are present in IMON but not in Monitors 3 & 4 . ASCII display of memory. What we find an attractive feature is that a line feed is used as a terminator for the display line thus making the display more readable. Set Breakpoint. This feature is not supported in the other Monitors. Up to three are supported. The effect is that when the breakpoint is encountered, execution of the machine language program being executed is stopped and the registers are displayed, as is also the address at which the halt was made. This is probably the most important feature if IMON is being used for debugging. Although one can always use as many breakpoints as are available, the support of three in this program is generous. TBUG for instance, only supports one. Write ASCII direct into memory. Characters from the keyboard are edited direct into memory. Disassembler. A straightforward disassembler to Z-80 mnemonics. Edit memory. Filler. Changes any stipulated memory block to a given value. Go with registers to last breakpoint and continue. Used in conjunction with the breakpoint feature described above. Printer set up. This command enables the printer for output from the Monitor. An important feature is that both parallel and serial printers are supported. A serial printer must be connected through the Tandy RS232C board and it is assumed that correct switch positions are set up on that board. Thus the Monitor interfaces a software serial driver routine with the hardware selected functions. Input utility. Inputs from cassette. One of the features of IMON is than an automatic or direct start routine may be recorded on tapes made by the Monitor (see below). The input utility therefore asks whether or not the tape to be inputted was made by the Monitor and, if so, whether the automatic start should be overridden. Jump. Jumps to a specified address and executes. Load data from tape to a buffer. Another useful utility. Input from the tape is loaded to a specified buffer area in memory rather than to its normal location. All data is loaded after the sync byte, including block identifiers and checksums. HEX display of memory. Output utility. Makes a tape of any required program in memory. The important feature is that an automatic execution trailer may be (optional) recorded onto the tape, the effect is that when the program is reloaded under the basic System command, it will execute automatically without the second asterisk appearing. Print speed. Valuable only with 'non-Tandy' printers. Printer set up disabled. Register display. Of great value is the ability to display the contents of the registers. The stack point is included. Search routine. Search a specified block of memory for a specified byte or bytes. Port control. Another new and useful feature. This routine continuously scans and displays the contents of all the 256 ports at the same time, on either the screen or printer. Furthermore any byte may be sent to a port. Verify. This routine verifies a block of memory with a tape. The tape must have been created by IMON. Write tape from a specified buffer. Mover. Moves a block of code from one location to another. It is important to note that this function does not relocate in the sense of changing any addresses of operands. It simply takes a block of code an puts it in a different location. Edit absolute branches. A final useful function not found in many other monitors. It carries out a disassembly but when it reaches an absolute branch, the program halts to give the user the opportunity to alter the branch address, whereafter the disassembly continues. This is a good monitor with only a couple of small criticisms too trivial to mention. If you need a monitor then the choice between this one and the others will be easy. If you are interested in machine language almost exclusively, then buy this one. If you need to interact with Basic as well buy one of the others. Memory Requirement 16k TRS-80 Tape Model 1 11-1217

TASK FORCE - THE COMPLETE PROGRAMMERS AID The 'impact' of this program is that it represents an extensive 'tool kit' containing every foreseeable feature that a Basic programmer could require, as he/she is add that it is not the definite solution to every programmers needs, such a program does not exist. As to little below, it is a compilation of some 21 separate utilities, each written by Nigel Dittman, and sold as a complete suite. COMMISSION: REMOVE REMARKS Remove all statements in a Basic program starting with REM Remove all statements starting with an apostrophe. Remove all statements starting with a REM number REMOVE SURPLUS CHARACTERS Remove all blanks, tabs and line feed the program statements, not those in any strings or disk statements. Remove all redundant links. Remove all blanks in data statements. Remove all redundant QDT's after TRDN Remove all LST statements. Remove all quotation marks at the end of lines, except in certain circumstances Remove all characters after the second in a variable name - thus WAGES becomes UK FACE THE PROGRAM Any of the following functions may be carried out: Face the lines together so that each line in its expanded forms will occupy no more than 240 characters. Inks will only be packed if they remain syntactically correct. The effect of this is to join what were single lines into multi-statement lines. Face lines into a sense format with no more than 240 bytes per line, but when expanded the line may well be longer than 240 characters. This remains a completely unavailable line. Specify the number of bytes to be packed. Depade the text. DENOTE TRACE The following functions may be carried out. Activate a Trace function with continuous display of the last 8 lines operated upon at the top of the screen. This does not use the normal TRDN feature of the Tandy Basic whereby the screen is effectively erased by the line numbers being displayed. The numbers are shown at the top of the screen. Remove the trace function . Activate the Trace with a line by line automatic pause . Activate the Trace with a stop by stop pause . Leave the Trace active, but suspend the display. The line number record will be kept up to date and can be inspected. Disable he Impact Trace function, but enable the Tandy TRDN. A number of pause options are available during the Trace so that during the pause, the user may pause and: . Display the current line . Display the current stop . Switch on or off the option to have the current stop displayed at all times . Enter Edit mode automatically in the current line . Alert the program . Clear the screen . Enter a breakpoint sequence . Breakpoints may be inserts in the program so that when the Trace reach them, it stops and all variables etc. are then available for inspection. FIND AND COUNT Locate the occurrence of a parameter specified by the user. The numbers of the lines containing the occurrence are displayed with the figure in brackets showing the number of occurrences in the line if greater than one. FIND AND WAIT Similar to the above but a pause is executed when the occurrence is found. A number of special commands are available including the ability to abandon the search, result from the first line, delete line display, automatically enter the Edit mode for the line displayed and continue to search. FIND AND REPLACE Again, similar to the above, but when the occurrence is found, it is automatically replaced by a user defined expression. JOIN LINES With this feature any line may be appended to another line with the automatic insertion of a colon. LINK CHECKING Any or all of the following features may be carried out. Mark all reference lines with a special form of the REM statement. Remove all marks inserted under above . Check all lines for referencing and display any error . As above, but append two asterisks for easy search COPY LINES Copy one line is another. If the line being copied into exists, it will be overwritten. The line copied is not changed. With this feature any existing line may be duplicated in another part of the program. APPEAR TEXT With this feature the programmer may close off the current program and enter from the keyboard or from tape or disk a new program. Thereafter the 'block' may be removed so that the program become one. DECODE LINES This is a useful feature which has come about by the continued use by programmers of the technique of entering graphics and machine language into packed strings. The feature will decode the strings into hexadecimal code and add them as new lines at the end of the program. A number of variations are available to this routine all of which are aimed at making the manipulation of packed strings more easy. GENERAL PURPOSE: DISK PROGRAM SHOREGOOD This function is provided to enable the quick saving of backup copies of programs during editing and debugging. It is only necessary to type in a three letter command for the program to be saved under the file name TEMPROLOG.Disk. This feature is only available under Level II Basic. EXIT FROM COMPAR Two exits are permitted. The first will restore all vectors and pointers intercepted by Camps to their proper states and then execute a return from Basic. The second exit is to ODO with or without a ODO command being appended. This feature is not available for Level II. REMEMBER PROGRAM LINES Essentially a normal renumbering program, with one or two extra features. STATUS REPORT Display is decimal the space allocated to the following: Program, Array names and values, String variables, Free space and Basic stack, Variable names and values, Total of all. RESCUE This feature will attempt to rescue a Basic program through an inadvertent reboot, or the inadvertent use of NEW etc. OBVIOUS, KEY FUNCTIONS Control keys are used throughout the program for various functions. The control keys are used to provide the following functions: Convert from upper to lower value. When set all display characters in the range ASCII 32 to ASCII 127 plus line feed and carriage return are copied to the printer. Screen display is not affected. This function duplicates the control 2 feature which is required in a number of programs particular in NEW2DO Basic. A convenience function returning ASCII values 01-95, which are the cursor keys and used in search options. IMPACT is available for Level II or Disk Basic and is compatible with current SYSTEM 80's Memory Requirement 16/32s TRS-80 Tape/Disk Model I & 3 Tape II-1258 Disk II-1258
