Alas, it fails with PV-Wave. Does anyone have a workaround?

kaveri 193% cat junk.pro
a = 1.0
b = 2.0
c = 3.0

kaveri 194% cat try.pro

pro try, x

@ junk
print, x + a
print, x + b
print, x + c

end

.....

Not good, eh? Thought it was my file try.pro that was the problem.
Turns out that it is not. Commenting the line out makes the file
'compile'.

I must say that the lack of this facility in very irksome. It is
one of the great adavantages of Python, which, though similar to
IDL/Wave has distinct advantages with namespaces, etc. There are
many times that I would like to call a Wave "main" programme
from another (just as I would Unix scripts) and not being able
means doing some of the work with Python, etc.
