Matcal contains four toolkit programs of real value to the games programmer.
AMSPICT is a drawing board for background graphics with menu driven editions. Save to tape, re-call and merge into your own BASIC program are all easily accessible.
Using infill to colour enclosed areas occasionally overran the perimeters and crashed the program.
AMSPRITE is a sophisticated character generator for sprite creation. The ability to design sprites of up to 40 x 40 Pixels in any of three colours. with a routine for animating them makes this invaluable for designing fast-moving graphics.
A menu-driven program with full save and recall facilities. The latter routine is complicated, but practice and patience are well rewarded.
FCOPY enables duplication of tapes, is quick and easy to use and records at either 1000 or 2000 baud rate. regardless of the original format.
AMSMON has the facility to enter and save short machine code programs and is a monitor giving access to the ROM and RAM memory addresses.
Accompanying the cassette is a comprehensive handbook in which explanation is followed by example.
Exceptional value for money.
