In short -- it works.
Why? Well, since I did not find any explanation about this message
the only option left was a check of the given examples, if they
still work. They do so. O yes, to obey the documentation exactly
has its advantages ;)

More lessons learned: in a .njp file, the pipe's name, obviously
the first word after the opening bracket after 'pipe', will define
the filename of the output file (filetype .class). Upper/lower
case matters (but that was outlined somewhere I remember).

Gain of plain pipe vs the pre-compiled: 1,7 seconds vs 0,2 what is
about factor 8, something less than the hoped for speed-up of 100
times faster.

That's a good moment to pause and judge this migration project.
Stop or go? Since for me it's hobby only, there is no gain to
compensate the effort. The only asset would be a program I
possibly /could/ publish. Alas, running somehow slow and with an
additional prerequisite to install.

Questions:
i) is there a chance to keep the java environment active to
achieve the 100x speed-up? For example start NetRexx and call from
it the yet available ooRexx routine?
ii) Is it possible to keep all pre-compiled pipes in one file,
comparable to a Loadlib? Otherwise there would be for each and
every pipe of a program an extra .class file. My objective is
typically to keep the number of files as low as possible.

Best,
M.
