Andrew Sharp from Oxford has put together a program that supplies Basic with a handful of useful commands. When run, the program saves itself as a binary file. This means you can use it later from your own programs: MEMORY &A4FF:LOAD"util.bin", &A500 will do the trick.
The extra commands are:
|XOR - inverts the colours on the screen.
|MERGE - merges two screens together. One is located at &4000, the other at &C000. The two are xored together. For example:
MEMORY &3FFF:LOAD "screen1",&4000:LOAD"screen2",&C000:|MERGE
|COPY.0 - copies the screen from &4000 to &C000.
|COPY.1 - does the opposite to the above.
|WAIT - pauses the computer until a key is pressed.
|REPEAT.ON - sets a key to auto-repeat
where k% refers to the key number (found at the back of the User Instructions or the top of the 6128's disk drive).
|REPEAT.OFF - does the opposite to the above.
|COPYCHAR - returns the Ascii value of a character at the current cursor position:
a%=0: |COPYCHAR,@a%:PRINT a%
|SHIFT - turns the shift lock on.
|CAPS - turns the Caps lock on.
|FLUSH - flushes the keyboard buffer.
|MOTOR.ON - turns on the cassette motor
|MOTOR.OFF - does the opposite to the above.
|HELP - lists all the rsx commands available
|BIGK - remember the BIGK formatter which appeared on the previous Christmas '86 cover cassette? Well, this routine makes it possible for you to load and save to the high capacity format easily.
|DATA - allows you to use standard formats again
