Adding Command Line-esque Parameters to C64 and C128 Programs

It's actually pretty easy to add support for command-line-style parameters to Commodore 64 and Commodore 128 programs by reading the line input buffer with some PEEKs. We examine how to do this, why this might be beneficial, and give some example code in BASIC and Assembly. We also learn a bit about how BASIC parses and interprets our code, and the internal structure of these commands and programs. And we look at the Commodore 128 feature to RUN a file from disk that further enhances the use of parameters. Download the D64 of today's code: https://8bitshowandtell.com/downloads...
