pipeing fucntions

[meino.cramer@...]

Hi,

(Warning! Newbie ahead!)

With UNIX systems you can build chains of cammands 
on the commandline eacht connected via stdout/stdin.

Is it possible to chain lua-functions in a similiar way, that is:
To create an output stream with one function which gets the
input stream of another function?

Is taht possible (portable...)?

Thank you very much in advance for any help!
Best regards,
