Re: [netrexx-pipelines] nrc is choking on variable substitution in my pipeline

[René J. <rvj...@xs...>]

Hi Leslie, Colin,

This source needs the pipes compiler - please try with pipc (pipc: aliased to java org.netrexx.njpipes.pipes.compiler) - it needs that step to sort out the variable inclusion. 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.

Best regards,

René.
