hm, | and ~ are always special, put \string in fron tof it, or use \letterbar and \lettertilde
hm, same error if I use \string| or \letterbar
do you have a minimal tes file?
a solution may be
\let\savedbarcommand=|
\unexpanded\def|{\savedbarcommand}
Yes, this works.
I've tried to create a minimal example, but in the end all points to the fact, that "|" is a special character. So even the use of "|" as argument of some macro like
\FOO[data={||abcx}]{..}
is not recommended (without prior catcode change). I use the symbols as an abbreviation for different MP graphics, and it wouldn't make sense to write \letterbar every time. Looks like I have to choose a different symbol.
still experimental is that you can change the catcodetable (pseudo in mkii, native in mkiv) but i won't bring up it's dirty details here \let\savedbarcommand=| \unexpanded\def|{\savedbarcommand} this makes them unexpandable but still using ~ and | for such purposes is kind of tricky Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
