[Oberon] Incremental evolution of piping system?

[eas lab]

No!
FeedTheDog; FeedTheCat; FeedTheChickens;
is not piping/FunctionalProgramming.

Piping/FP is were the input to stage N is supplied by a previous stage.
My above [not function] example is a sequence of independent Procedures.

A further example of what IS piping/FP:
 before I  restored a Linux system and was forced to use M$, the TextToSpeech
needed to:
RemoveAll <EndOfLine> | RepaceAllBy(%, percent) |
ConvertText2wav(TxtFile,WavFile)
 | ConvertWavToMp3(WavFile,Mp3File) > Outputdevice

Then I discovered the M$ system says: " em <pause> are <pause> Jones",
 instead of: "Mister Jones".
So I need to insert a FP/piping-stage, which has input:
The-being-cleaned-up-text,
 and output the text with "Mr." fixed.

*Importantly*  FP/piping gives extreme modularity: ie. the <Fix Mr.> stage needs
no knowledge by the user of how other stages work.
