Thanks Rene

I am still a little confused though.

I have a file called testpipe.nrx which has been copied from the 
Pipelines Quick Start manual

z:\NetRexx-4.01-GA\bin>type testpipe.nrx
class testpipe

method testpipe(avar=Rexx)

  F = Rexx 'abase'
  T = Rexx 1

  F[0]=5
  F[1]=222
  F[2]=3333
  F[3]=1111
  F[4]=55
  F[5]=444

pipe (apipe stall 1000 )
stem F | sort | prefix literal {avar} | console | stem T

loop i=1 to T[0]
  say 'T['i']='T[i]
  end

  method main(a=String[]) static

  testpipe(Rexx(a))
z:\NetRexx-4.01-GA\bin>

My understanding is that I am supposed to use pipc to compile it.

z:\NetRexx-4.01-GA\bin>pipc testpipe
  16 +++ stem F | sort | prefix literal {avar} | console | stem T

Hmmm.. . . maybe I am supposed to call it testpipe.njp.  Let's rename it.

z:\NetRexx-4.01-GA\bin>
z:\NetRexx-4.01-GA\bin>rename testpipe.nrx testpipe.njp

This looks much more promising.  Let's run it.

z:\NetRexx-4.01-GA\bin>
z:\NetRexx-4.01-GA\bin>
z:\NetRexx-4.01-GA\bin>java testpipe
Error: Unable to initialize main class testpipe
Caused by: java.lang.NoClassDefFoundError: org/netrexx/njpipes/pipes/ThreadQ

That didn't work so I wonder if I am supposed to execute the 
testpipe_apipe.class instead.

z:\NetRexx-4.01-GA\bin>java testpipe_apipe.class
Error: Could not find or load main class testpipe_apipe.class
Caused by: java.lang.ClassNotFoundException: testpipe_apipe.class

z:\NetRexx-4.01-GA\bin>

Not sure what I am doing wrong.

Thanks
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.
