Had a PostScript function calling "join" that was defined later on in
the same dict, running it on Ubuntu GPL Ghostscript 8.70 (2009-07-31).
Didn't work at all. After a looong debugging session I found out that
there is a "join" defined as an operator in systemdict, and the "bind
def" of my function was hooking up with that.

Solved the problem by renaming the local "join", but - just curious -
what is this operator "join"? What does it do? Adobe seems not to have
it. Too lazy to download the sources.

Thanks,

Olle

It appears to have been removed in PostScript level 3, its defined in
the level 2 specification. It joins two execution contexts, its a
Display PostScript operator as printers only ever have one context.
