Hello all, I have problems to understand the command (parameter) mechanism of context. My experiments with \getparameters didn't work, so I used \xdescgetparameters from Giuseppe Bilotta (t-xdesc.tex). In my eyes they look the same, but \xdescgetparameters works with my sample code, \getparameters don't. Mhhh.... % t-xdesc.tex \def\xdescsetvalue#1#2{\expandafter\def\csname#1#2\endcsname} \def\xdescgetparameters{\dogetparameters\xdescsetvalue} % syst-gen.tex \def\dosetvalue#1#2% #3 {\@EA\def\csname#1#2\endcsname} % {#3}} \def\getparameters {\dogetparameters\dosetvalue} This leads me to my two questions: What must I change, to make my test example run with \getparameters? Where is the error in my \docommand? All parameters but [height] work and the tracing output at this parameter (\OTRSETshowstatus) says nothing to me. Thanks for any help, Peter P.S.: using miktex 2.3, context version 21.08.2003
