Mochasoft and Mac OS 9.1

I apologise for my earlier positng with the wrong subject!!!

I posted the message below on PC-Tech but only got a response relating
to MAC OS X.

A client wants to use mochasoft 5250 emulator on a Mac with newly
installed Mac OS 9.1.
He has downloaded and installed the Mocha emulator but none of the
function keys work and he gets a MAC OS 9.1 message about programming
the function keys if he presses any of them.
Is this how it should be?  A quick glance at the Mocha help showed that
it told you how to change keyboard mapping within the emulator but not
that it was necessary to map them in OS 9.1 before you could get the
emulator up and running properly.

Has anyone any experience of using Mocha with Mac OS 9.1?

The response that I received relating to OS X stated that Mocha ran
under OS X "out of the box" without any set up being necessary.  This is
what I would expect under OS 9.1 but the Mac software house who
installed 9.1 (without my knowledge) say that function keys have to be
enabled in each application that uses them in both 9.1 and OS X, even
for instance for IE.

Many thanks
