Database 500, for double-sided disks, and Database 300, for singlesided disks, is the first non-exchange program offered by the International TI99/4 Users Group. It is.also the first module of its Maste 99 series, designed for "serious applications of
the Texas Instruments 99/ 4(A) Home Computer in extensive home or small business environments," according to the IUG magazine Enthusiast'99.
Database 500 comes on a disk and consists of five unprotected programs written in Extended BASIC:
::(1) Load
::(2) Main program
::(3) Print routine
::(4) Sort routine
::(5) Subfile selection routine
Database 500 stores about 500
records on a double-sided floppy.
Database 300 stores, about 300
records on a single-sided disk.
Database 500 permjts users to
create records that consist of up to 16
fields containing a total of eight
screen lines of data. The files can be
sorted along any field or in combination,
which makes it very useful for
cataloging. Printing, too, is very
flexible. The user can decide not only
which fields to print, but where to
print them.
Performance: Database 500 does
exactly what IUG says it will do.
Because it uses relative files to write
directly to disk, users, may store a
great deal more data: than can be
stored by programs such as Texas
Instruments' Personal Record Keeping
cartridge, whose capacity is that
of memory available in the 99/4A
console.
The program loads automatically
out of the disk when' you go into
Extended BASIC. After initializing a
file disk-Database 500 uses all 716
sectors of a double-sided disk-you
load the main program. This is the
workhorse part of Database 500. Thispart
of the program ine;ludes the following
six functions:
1. Enter Records
2. Update Records
3. Display Records
4. Scan Records
5. Repair Files
6. Create Record Files.
You must choose function six at the
very beginning. After loading a blank
