Long ago, I asked for any public-domain spreadsheet with sources
available. Here is what I learned:
1) Turbo Pascal comes with the source for a demonstration spreadsheet. I
phoned Borland, and was told that they would have no quarrel with my
intention to translate their spreadsheet program into C (which I've
never gotten around to doing), but that they'd feel badly if I took their
source to compile it on someone else's compiler. The source code itself
begins with a declaration that it's in the public domain.
2) Someone forwarded to me a shell script for generating a program variously
identified as SC or TC, originally by James Gosling, modified by
Mark Weiser and Bruce Israel, Univ. of Maryland. While I don't speak
shellish myself, most of it seems pretty straightforward. The sticking
point for me is that the nitty-gritty - the parsing - is represented
by a page or two of BNF that, I gather, is supposed to be chewed on by
LEX and/or YACC, neither of which we have on our Crays.
3) Two people referred me to "vc", a spreadsheet in C posted to
net.sources. I'd appreciate advice on how to get at it.
