nathanriggs f5c097e70f STDIO disk 0.3.0 update
- added error handling
- no more massive library; just a subroutine per file. This is because Merlin doesn't like large files.
- added a "minify" BASIC utility that gets rid of *most* comments in a source textfile. This dramatically reduces space used if you're not terribly interested in non-inline comments.
- TFILL,THLIN,TVLIN and TPUT not directly access the video memory (page one), making for a much faster draw without interfering COUT.
- some stylistic changes, primarily to TFILL
- change required files to minified versions only. The whole files can be found on disk 2.
- got a norovirus so pretty much couldn't do anything requiring sustained attention, so focused on small things here and not on my dayjob. Cool.
- created a required.vars file that separates variables and settings from the other required files. Not minified.
- This current bout of revision will probably be the last, once all initial 6 disks are revamped, that focuses on all subroutines/macros in a given library at a single push. After this round, commits will be done on a subroutine or related file basis.
