... 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. - Peter. (pearson@lll-mfe.arpa)
