Well, I can rather agree on the uploading, but I don't find it quite as bad as you do. Not as good as NQC, but then NQC still has all the LEGO firmware limitations. As for the rest of your comments, I can only say that I managed to get the (...) (25 years ago, 9-Jan-00, to lugnet.robotics.rcx.pbforth)

So I've just been crawling over some broken glass, ERR, I mean, uploading pbFORTH text files to the RCX! It's hard to tell the difference! At the least, pbFORTH needs to: 1) accept \n, \r, \n\r or \r\n all as it does a single \r now. 2) have a mode (...) (25 years ago, 8-Jan-00, to lugnet.robotics.rcx.pbforth)

How about a Forth based environment running on the PC? It would not be that difficult to move the RCX based compiler to be a cross compiler on the PC. One would be able to run in two modes - "native" through a Forth based terminal (...) (25 years ago, 2-Jan-00, to lugnet.robotics.rcx.pbforth)

Last night I tried to install pbForth 1.11 with nqc (2.02). It beeped like it was installed and "4th" was displayed on the screen, but I could not turn it off.
