Anyone know how to exit the TECO text editor? The `EX` command I found on a manual[1] doesn't seem to be working: teco ZEX$$ BAD E Z-1EX$$ BAD E Z-1EX $$ BAD E Z [1] http://www.copters.com/teco.html#RTFToC159 http://www.copters.com/teco.html#RTFToC159 EDIT: Got it :P Z2+3$$ Z1/0$$ Error: Attempt to divide by zero at teco$|2051 (>system_library_tools>bound_teco_) system handler for error returns to command level r Guest.Guest:>process_dir_dir>!BNLFBlpbBBBBBB 11:44 05/12/21 0.193 5 level 2,13 Guess I have to read more to understand why it's putting me in a math expression evaluation (?) `Z` prompt (which I haven't found mentioned in a manual) rather than the `*` command prompt. EDIT 2: Seems `eq` is the proper way to exit on this TECO: Zeq$$ r Guest.Guest:>process_dir_dir>!BNLFBlpbBBBBBB 11:56 05/12/21 0.034 3 level 2,13 I don't see that mentioned in other manuals online. I guess this TECO is different from others?
