Hi, I try this example from the wiki page System Macros/Argument handling: \def\dodefinesomething[#1][#2]% {\getparameters[\??xx#1][#2]} \def\definesomething% {\dodoubleargumentwithset\dodefinesomething} \starttext \definesomething[alfa][variable=test] \stoptext Running this yields ! Undefined control sequence I'm trying to write a few macros with optional delimited arguments with key-value sets and started reading the appropriate pages, but can't figure out why this example fails to run. Anybody any idea? Regards, Gerard Verhaag
