Ahoi MP experts,
i've tried to implement a keyval-interface in MP.
Currently it looks like
def keyvalFunc (text t) =
begingroup;
save status, col ;
numeric status; string col ;
t ;
show status;
show col ;
endgroup;
enddef;
keyvalFunc(status=1.0; col="Hallo" ) ;
This works, of course, but i would prefer if i could
use a comma instead of the ";" to separate the keyval-pairs.
Any ideas, how i can make "," be locally like ";"?
Thanks in advance.
Jens

Perhaps
begingroup
let ,=;;
endgroup
will do the job.

Alle spørgsmål er lige dumme.
Og spørgsmålet "Kan ænder flyve?" er ikke dumt.

Thanks. I've already tried this. The problem was that it changes
the meaning globally, since MP groups do nothing until one 'save's
variables inside the group. But surprisingly (for me) this works:
begingroup
save , ;
let ,=; ;
endgroup
