If you expect TC16/PM/32 to be the same as 4DOS/4OS2/4NT, you would be sadly mistaken.
But you can use it to host command-line utilities and rexx scripts, and that it's more 'gui' than 4dos/os2/nt means you can resize the window freely, and use it as a source for cut and paste into other documents. I have a copy of tcmd32 sitting on the quicklaunch in windows 2000 especially for that end.
But yes, i remember caveman too. Jolly good bloke.
