Is there *anything* in the world (excepting microsoft) for which the NOT
operator does not precede other other logicals?

It is more and more maddening.
I've tried this, and get the same error.
And to make matters worse, the error does not bite if I single-step
through; only if the program is running (and apparently only if the
condition is true!).
At the moment, the code looks like:
put (the prgVrsn of stack "mcp")
put (the prgVrsn of stack "mcp") <> progVersion
all of which have no problem, and then
if (the prgVrsn of stack "mcp") <> progVersion then
causes the IDE to choke
