Message-ID: Date: 9 Oct 89 15:00:26 GMT References: <8910090133.AA09674@violet.berkeley.edu> Organization: Rutgers Univ., CCIS Lines: 11 I did one as a proof-of-concept under VM/CMS using XEDIT for the screen manager. All the underlying code is in REXX, no Assembler, no C, no nuthin'. It ain't fast, and it ain't pretty, but it was fun to do. As you say, REXX is a natual for this. The content-addressable arrays work very nicely as a sparse-matrix structure, so you don't have to over-allocate memory. The ability to set a default value for all variables with a common stem means that you don't have to special-case the handling of non-existent cells in the matrix. All in all, not a bad toy.
