Changes
/* CPC specific version */
The first of the tape and disc versions was lacking functions to control the special features of the Amstrad CPC. Functions like sound, graphics and software interrupts. To use the specific functions small modules was released so the programmer could include them in their own COMAL80 programs.
Finally a greatly enhanced version was released. This version occupied three 16Kb eproms. Extensive graphic/sound/timer commands was added together width extended FILE I/O(Random Access File) and the ability to use both [[Dk'tronics memory expansion|DK'tronics ]] and [[Vortex_Expansions_RAM_card|Vortex memory expansion ]] as ram discs or graphic swap space (to use width the advanced windows features). The ROM version was shipped with its own [[ROM board]], micro switches controlled whether to boot directly into COMAL80 or to make the ROM board invisible to allow native CPC programs to run. It is unknown if COMAL80 would have worked on a standard ROM board.
The Danish magazine [[Amstradbladet]], ran a series of articles called "The COMAL school" to teach its readers COMAL80.
