[MacPerl] How to use toolserver ?

[Thomas Miller <miller@ps.lhag.de>]

Hi,
I try to understand the short remark in MacPerl.html that
"MacPerl has a limited capability to handle constructs like 
`command` or open(F, "|command") , if you
are the lucky owner of ToolServer."

How does this work ?
Not technically, I mean : MacPerl sends an AE, ... - but:
how do I actually USE it ?

My goal is to incorporate the MPW tool isql into MacPerl in order 
to access a Sybase database.

Yours
Thomas Miller
