Hi, the vertical line symbol "|" (pipe) breaks \processaction (no problem with the latest stable version). The minimal example at the end of this message results in: [..] systems : begin file processaction at line 3 !

do you have a minimal tes file? a solution may be \let\savedbarcommand=| \unexpanded\def|{\savedbarcommand} ----------------------------------------------------------------- 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 -----------------------------------------------------------------

not any longer...
a solution may be
\let\savedbarcommand=|
\unexpanded\def|{\savedbarcommand}
I'll try this tomorrow and also try to make a new minimal example. Thanks anyway, Peter

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. Greetings, Peter

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 -----------------------------------------------------------------
