Re: [Flashforth-devel] ff-shell3.py question

[Mark E. <mar...@gm...>]

Hello Mikael,
OK…so chalk up this mostly to operator error..

the only thing I *really*  needed to do is create the “.ff.history” file before running the script.

the “missing file” error message I originally ran into was caused by that *but* I went down a rat-hole thinking there were other issues.

at one point though I did get the error message about  "local variable 'e' referenced before assignment”  BUT that is gone now and I cannot explain why except that maybe while playing with the code I did something bad..

but right now its working fine.

On to the tcl script though I cannot get that to work on my M1 MacBook air for some reason even though tcl/tk is installed.

i’ll start a different debug thread on that.

thanks
mark
