Thanks Rene
I guess I must have something set up incorrectly in my environment.

I wonder if it is because I am using Microsoft OpenJDK implementation.

In fact this may indeed be the problem.

I thought I had tried this before. . .something has mucked up my
environment.
I also cannot find any detailed description of callpipe and addpipe.
They just magically appear in some of the examples with no prior
explanation.
I will look at rebuilding my environment from scratch with a different
JDK to see if that helps.
Thanks again for your help.
Cheers
Colin

Colins analysis that the NetRexx compiler cannot handle this is correct. If you can include a version of the source that does not include | (pipes) at the start I can easier check that for you.
