RE: getch always returns -1 after shell

[jon wackley]

Hi All,

Thank you everyone for your help.  Having no debugger I was forced to
instrument the executable piece by piece.  This was painfull.  Though the
practice was banished some time ago, I tracked down a piece of code that was
executing scripts asynchronous *SIGH*.  Executed the scripts synchronously
and everything worked.

BTW - did not need def_prog_mode after all.  Just to let you know I found
the def_prog_mode in a shell example somewhere in the documentation, if it
really isn't required then references to it should be removed.

Thanks again,
jonw

the "always" is a little unclear - "always" on the first occurrence, or
even on repeated calls?
