Colecovision Almost-like-magic BASIC compiler: CVBasic v0.7.0 (now with TI-99/4A support!)

[artrag]

Just tested v7.1 with the new CALL and USR.

The generated ASM is maybe abusing of PUSH/POP when loading registers passed as parameters but works fine 💪

For anyone interested there is now support to read the VDP status register (cached at interrupt time) using the VDP.STATUS syntax.

 

Also, I've updated the example face_joystick.bas to show how to use it.

 

Available from the source code git https://github.com/nanochess/cvbasic

Another thing I wanted to do since a few months: SELECT CASE / END CASE.

 

It accepts CASE expr, CASE expr TO expr, and CASE ELSE.

 

Added an example test3.bas to show the usage.

Another thing requested by people using assembly language: CONST values are now exported to assembler.

I've updated the Space Attack example to show a smooth-scrolling stars background.

 

This is a technique where the screen is covered with endless vertical strips of 8 characters. Only these characters are redefined for a whole screen scrolling.
