Lines: 27 I saw microshell once, and was impressed by the similarity of the user interface with UNIX's. It implemented pipes by redirecting I/O through a temporary disk file and seemed to work fairly well until you needed to change the disk with the pipe file on it. This of course wouldn't be a problem on a hard disk. If I might make a suggestion, look into the ZCPR3 package on Simtel20 or your local computer BBS. It implements a rather large part of the Unix user interface, adds TERMCAP capabilities, a nice shell package with variables and parameter substitution similar to csh and some limited flow control. (If-Then-Else) But no CASE WHILE and UNTIL. Still some pretty involved shell scripts are possible. It does not offer I/O redirection or pipes, however the company handling bug reports and distribution of a self installing version ,Echelon inc., have hinted strongly that their new version of the BDOS will do just that. The best part is that if you can find a local BBS that has it you can get it FREE by just downloading it. That includes copies of a zillion utilities. It does make the CP/M user interface usable, but you will need a Z80 to take full advantage of it. --Chuck -- - - - D I S C L A I M E R - - - {ihnp4,fortune}!dual\ All opinions expressed herein are my {qantel,idi}-> !intelca!cem own and not those of my employer, my {ucbvax,hao}!hplabs/ friends, or my avocado plant. :-}
