[IntyBASIC] Creating and printing packed strings

[GroovyBee]

Heres a quick and dirty example of using an assembly language macro to create a packed string and a function to display it on screen. The string can contain upper and lower case letters, digits etc. and is restricted to the first 8 foreground colours for the GROM font.

 

Screenshot:-

 

The source code:-

BString.bas

 

The ROM:-

BString.rom

 

If you put the ROM into a hex file editor you can see that the strings are packed in a human readable format.

 

Any questions or problems, let me know.

 

Enjoy!

 

@nanochess: Feel free to include the example in the next release of IntyBASIC.

I've spotted a comment started with ; when testing with IntyBASIC

 

Edit: also added along your 4-pixel wide font thread to the IntyBASIC compiler resources thread.

Grrr! Well spotted! I'll fix that in a moment.
