SIMULATED COMPUTER This program graphically simulates the internal operation of a small computer. Students can input and run programs, seeing the results of each operation and how it is logically interpreted inside the computer, right on the screen. The program displays messages describing what it is about to do, and provides descriptive error messages. A five-lesson tutorial and reproducible manual are included. Available on 32K disk for the Apple II; and on 16K cassette for the TRS-80 and Atari.

Software Profile - Algebra Series, Microcomputer Workshops. In the Simultaneous Linear Equations program, the student is presented with two equations, each in the form AX + BY = C and asked to solve for X and Y. All of the coefficients are integers and all of the solutions are integers which fall into the range of -5 to +5. To solve the equation, the user must first transform one or both of the equations so that the coefficients of one of the variables are equal or opposite. Then the equations must be added or subtracted to eliminate one of the variables. The resulting equation must be solved for the remaining variable and that value substituted in either of the original equations to determine the value of the other variable. Once the user has solved the equations, the program performs checks in both equations to show that the values are correct. In addition, the two equations are displayed as line graphs showing that the solution is the point of intersection of the two lines. An error tally is maintained. The documentation with the packages from Microcomputer Workshops is explicit and includes objectives, a program description, and a demonstration problem.

SIR - SELECTIVE INFORMATION RETRIEVAL SIR is written by Gordon Hatton who wrote Instant Sort Search, which is described on page 31.1 of this catalogue. If you are not familiar with ISS, it may well be of use if you turn back the pages and read the description; not because the present program is an update or upgrade of ISS, but because SIR is so big a database concept that it is required a sort written for it and what better than the ISS concept which has proved to be a Benchmark for fast sorts. SIR is not only a database but a new approach to database structure. Up until now, there have been two important categories of databases, one planar and the other relational. The former is the original type of database written for microcomputers. Everything in a planar database is held in one level. The base is split up into records and the records into fields. It is entirely structured. Although one can Search, Sort, Edit and so on, using the contents of a field as a key, one cannot cross the single layer boundary of one single layer to another. A relational type database is non-planar. Each field is kept as a separate record. Perhaps the name is one, the address another, occupation another and so on. One file contains all the names, another all of the occupations. The database is constructed by linking this data together. The advantage of this is self evident. One is not restricted to a particular record. The data is stationary, the links are moveable. But now SIR has come along creating yet a third concept. SIR is to data what Visicalc is to numeric information. SIR has a number of similarities and might be described as an electronic analysis book. Just as in Visicalc, the screen is a window on a large matrix or spreadsheet, so SIR provides a window on to an enormous analysis book. With SIR we are dealing with data which is normally alphabetic - but may be numeric, rather than the reverse. The data in the analysis book may comprise an entire disk. The great drawback of an 8 bit microcomputer, namely that far more data can be stored onto the disk than can be brought into RAM, is overcome by SIR. With the advent of the 16 bit machines, this problem is slowly disappearing but until recently all microcomputers were restricted to some 30 or 40K of RAM in the machine, yet could access hundreds of thousands of bytes on the disk. Supposing one has a written analysis book used as a record book; an executive would pull out a pad and jot down the entries in the columns that are relevant to his application. Suppose, for instance, the first column is for name and then 15 columns of information are needed to record sex, age, branch, salary and so on. If our hypothetical executive is interested only in knowing the names of people who fit certain categories he may sit at his desk, run his finger across each name, check each column and jots down on a sheet of paper the name, sex, salary and so on. This is precisely what SIR does. From the database (which can fill an entire disk) it will (in a manner similar to ISS) effectively construct a sub-set database fulfilling the criteria which he has decided upon. This is a big idea and is tremendously powerful. For once the selection has been made - and remember this is a sub-set, we are not now dealing with the main database, we have now selected from it what we want - our executive has full powers of manipulation; in particular the fantastically fast Sort previously mentioned, the ability to printout, delete, amend and so on. In many respects SIR is similar to the relational database. SIR comes with a demonstration staff file database on the disk. SIR is just as happy (and efficient) at constructing a file about branches - who works in which branch, how much they earn and so on - as a file about categories, who falls into which, in which branches are they found, job categories etc. The examples that one could mention are literally endless. A customer file may contain columns for sales 'regions', 'representative', 'total orders in the last three months'. From this SIR can produce a list of inactive accounts analysed region by region, representative by representative and each representative's accounts in alphabetical order. The power of SIR is that all the user has to do is select the columns he is interested in and he effectively has a sub-set database upon which he can carry out any manipulation. There are probably millions of permutations in column selection. There are very few restrictions in the program. The most important is that a database in size cannot exceed one 40 track disk in single density on the Model I and in double density on the Model III. If this is considered to be any sort of a drawback, then the database can be split up into subject categories by the user. Obviously the further restriction of the amount of RAM available is true but in actual use this is not considered to be penalty. One has in excess of 30K to play with an one is talking about the window or sub-set, not the entire database. We must make it clear that SIR is not an update to ISS. Hence, there are no update privileges available to present owners of ISS. However, Mr Hatton has been kind enough to supply us with a Basic utility which will enable owners of ISS to upgrade their disk files for use in SIR. This is provided free on the distribution disk. One other small bonus is that SIR files are straight ASCII and can be manipulated by most word processors.
