THE INSIDE TRACK The Inside Track is a simulation of a Horse-Race meeting designed to provide very realistic spectator participation. The graphics are clever and amusing and the track meeting, while sufficiently true-to-life to intrigue racing fans, provides many levels of entertainment, from betting for fun, to training in analytical investment for real track use. There are no pre-programmed or random results and the odds against a particular race meeting being re-created are quite astronomical. Each race is run in real time with the outcome subject to the same imponderables as the real thing. Horses and riders compete according to their known abilities and are affected by track conditions, distance and weight carried as well as the tactics of the other riders. Holding is certain in the world of horse racing. There are always unknown factors that influence the performance of a particular horse, and The Inside Track's major and unique attraction is that these unpredictabilities are programmed in. HORSE: The Inside Track has a large resident stable of named, classified horses - 750 in the disk version - each with clearly defined performance characteristics. These pointers allow you to assess the probable performance of an individual horse under the race and surface conditions prevailing at that time. RIDER: The register of named riders and apprentices includes some very crafty tacticians and the ability of some of the riders will become apparent with familiarity. HORSE PERFORMANCE POINTERS: Indicate a particular mag's strengths. For example, the ability of a horse to accelerate in conditions where the track is soft or heavy, or the horse's starting capability or his ability to make a strong run in the later stages of the race; all are available for your assessment. TRACK SURFACE: It is possible for the track surface to change slightly during the race-meeting - a strong wind and warm sun might dry out a wet track and heavy rain can soak a dry one; watch the up-to-date track surface reports. DISTANCE: Race lengths can vary from five furlongs to one mile (a furlong is 1/8 mile). A short distance will sometimes give a fast-starting horse a significant lead with stronger-finishing horses unable to get themselves positioned in time to bridge the gap. TOTE INDEX: After the field has been posted on the race-board, the calculated off-course betting levels produce Starting Odds for each of the entrants which are displayed under the heading of 'Tote Index'. If, for instance, the number displayed is a '2' then the payout odds for a SHOW bet are 2-1; for a PLACE bet double that at 4-1, and the odds for a WIN bet will be times three, or 6-1. The 'Tote Index' therefore gives a sort of order-of-favouritism for the race and can often be a guide for choosing a winner. It can also give valuable information for identifying a 'dark-horse' with the odds good for perhaps picking a certain 2nd place or 3rd or BETTING: The Member's Stand provides betting windows from $10 to a 'million dollar' window and deposit and bet sequences are straightforward with instructions available between races. Where the gambling laws allow, a 'pool' facility is provided for users who want real betting facilities and a house percentage may be retained. Once a bet is laid, the indicated account is debited. A successful bet has the original stake returned in addition to the winnings. BET TYPES: A WIN bet means a payout only if the selected horse wins the race. A PLACE bet pays out if the chosen horse comes first or second. A SHOW bet pays out for first, second or third. A QUINELLA bet allows you to select two horses in the same race, and if they come in first and second (any order) then you collect. DOUBLE chance and TREBLE chance multiple bets (Double on races 6 and 8-- Treble on 5, 7 and 9) must be instituted on their first leg (race), and you will be invited to supply your choice for that leg only. If your first choice is successful then your multiple bet stays 'live' and after returning to the window on the next leg and entering your account number, you will be given the opportunity to supply your next choice BETTING ACCOUNTS: 16K (TAPE) version betting accounts are all initialised with $1000 (32K version by deposit). 16K version accounts retain their balances after the 9th race while the program initiates a new race meeting. A Master Menu provides access to the account balances between races, and the display also indicates any 'live' multiple chances. In making a bet, indicating your account number causes the account balance to be displayed by the betting window. Attempts to bet a stake larger than your account balance will be refused. Don't be worried by the size of some of the bets- the accounts will happily handle balances in the billions of dollars, but beware - big bets can mean big losses and your betting account will just as happily tell you that you're broke!!! TECHNICAL DESCRIPTION: 16K (TAPE) version- program length 13288 bytes 150 horses, 60 riders 32K (DISK) version- program length 26733 bytes 750 horses, 150 riders The Inside Track is written in Microsoft LEVEL II BASIC with imbedded machine-language graphics and race logic, and random access horse and rider files. The M/L routines are situated in a rigidly formatted BASIC line structure, and use no ROM calls. A self-crazing locator module provides proper location to suit the start-of-BASIC address, and the graphics RAM is also located within the program structure. Horse and rider file records are contained in BASIC lines, and use a special form of compression which effectively halve the memory space normally required. The program is not BREAK protected, and may be stopped and re-started without strife but the code is self-modifying and should not be saved after it has run. It's up to you now .

INSTANT ASSEMBLER The INSTANT ASSEMBLER is a powerful disk or tape-based assembler and debugger for the TRS-80. Now you can assemble directly to memory and immediately debug your program with the built in single stepping debugger. Quickly switch from assembler to debugger and back again without losing the source code. This feature makes INSTANT ASSEMBLER an excellent learning tool for assembly language programming. INSTANT ASSEMBLER is absolutely unique among tape based assemblers in that it produces relocatable code modules that can be linked with the separate LINKING LOADER, which is supplied in two versions for loading programs into either high or low RAM. This lets you build long programs with small modules. INSTANT ASSEMBLER also features immediate detection of errors as the source code is entered, a compactly coded source format that uses 1/3 as much memory as standard source, and many operational features including single stroke entry of DEFB and DEFW, pinpoint control of listings, alphabetic listing of symbol table, separate commands for listing error lines or the symbol table, block move function, and verification of source tapes. INSTANT ASSEMBLER's debugger provides single stepping with full register displays, decimal or hex entry of addresses, forward or backward memory displays, disassembly of object code in memory, memory display in ASCII format, and hex-to-decimal or decimal-to-hex conversion. The single-stepper will step one instruction at a time or at a fast rate to any defined address. INSTANT ASSEMBLER occupies less than 8400 bytes of memory. In a 16K machine this will leave you enough memory to write assembly language programs of around 2000 bytes. This and its module-linking feature make INSTANT ASSEMBLER ideal for users with only 16K machines. The instruction manual may be purchased separately for $5, which will apply towards the purchase of the INSTANT ASSEMBLER. In addition to disk I/O, the disk version includes a stand-alone version of the debugger program MICROMIND. Specify Model I or Model III. TAPE INTASM $29.95 on tape Specify Model I or Model III.

INSTANT Sort and Search UNBELIEVABLY FAST! Everything in electronics takes a finite time, consequently nothing can be instantaneous. However, a database that will search 500 records and sort the names into alphabetically order in 1 1/2 seconds, that will go on to do the same thing with 1,000 names in only 2 1/2 seconds, is fast. If you add to that the ability to search 500 or 1,000 records for a specific range of names or ages or sexes or whatever, in such a small amount of time that it is not worth timing it, then the program deserves to be described as instantaneous. Especially as these times are attained on a standard Level II TRS-80. These results are achieved, obviously, by some very clever machine language coding. The reason is that this program was designed from the outset to achieve unbelievably fast sort and search times. Indeed we do not recommend this database for applications in which fast sorting or searching is not a prime requirement. The type of application for this type of program is practically unlimited. If you are looking for a program that will retrieve information at the virtual touch of a button, then INSTANT SORT AND SEARCH is the program you require. Be the application a club membership, a telephone enquiry system, an Estate Agents file, or as a means of indexing your stamp collection, the information is returned quickly and precisely. The prime commands and features of this program are as follows: DATAFILE CREATION . Create a file . Add a record . Display a record . Delete a record . Store a file . Amend a record . Display the file data . Load a file SORT/SEARCH . Sort up or down . Page forward or backwards . Select a range for search . Select or exclude a category . Select or exclude an initial letter . Resort records in a sort . Sort all new records . Extended sort . Arithmetic . Display file data . Load a file . Printout sorted data The data is displayed in columnar form and may be alphabetical, alphanumeric, integer or decimal. The number of columns is from 2 to 10 and each record may contain a maximum of 60 characters depending upon the number of columns used. Columns may be exchanged, deleted, extended, reduced, or a new column created within the file. Columns may be of any width within the screen capacity but integer or decimal columns more than six characters wide cannot be used to search within a range. The program consists of two parts. The first is used for entering data and the second for sorting or searching. The second part overlays the first when it is loaded so only 4k of memory is used by the entire program. The remaining memory space is available for your data. The amount of data that can be stored will of course depend upon the amount of memory available, a rough guide is that a 16k user will be able to manipulate at one time 250 records of 39 characters each or 514 records of 17 characters each. As a rough guide to sort speed, the time to sort 1,000 records on fields of random strings of random length, or of random number between 1 and 99,999 averages under 2 1/2 seconds. Numeric columns either integer or decimal may be arithmetically manipulated almost instantaneously. A total may be cast or an average taken for any numeric column up to five digits. This is so fast that when adding 1,000 numbers totalling over 50 million, only a slight hesitation can be noticed before the total is given. The disk version of this program has been made fully compatible with TRSDOS, DOSPLUS, LDOS, and NEWDOS. Memory Requirement 16/32k TRS-80 Tape/Disk Model 1 & 3 Tape 11-1605 Disk 11-1606
