Pecom 64 BASIC 1.0 & 4.0
Commands
All Pecom 64 BASIC 1.0 and 4.0 Commands including some of the start addresses of these commands are listed below. Try for example CALL (@B301)"HELLO"; this will do the same as the PRINT command. Click on the command itself to get a description of command format and usage.
I guess two interesting routines for people from Serbia:
CALL (&CE00): Switch to Cyrilic character set
CALL (&CE70): Switch to Latin character set
