Save the below text as hello.cbs:
@OPTION TARGET c64
CLS
POSITION 0, 0
PRINT "HELLO, WORLD!"Compile it to assembly:
crustybasic compile hello.cbs -o hello.sBuild a runnable C64 .prg in one shot. This needs a compatible assembler
(like vasm); see USAGE.md#assemblers.
crustybasic build hello.cbs -o hello.prgScreenshots and emulator captures live in screenshots.
Please submit bug reports through the GitHub Issues tab. Include the CrustyBASIC version, your operating system, the target or system you are building for, the command you ran, and any compiler or assembler output.
Small self-contained .cbs files are the easiest reports to reproduce.
