Dear All, I am hacking the context index entry rendering... ;-) ... but I am stuck with a simple comparison How can I test the given entry if it equals to the specified one? The following code has no effect. \unexpanded\def\defaultregisterentry#1#2#3#4% % #1:processor #2:internal #3:seeindex #4:word {\def\currentregisterpageindex{#2}% % start hacking \def\myword{#4}% \ifx\myword{My Primary} \column % do something \fi % stop hacking \strc_register_injector_process ... What is the proper syntax? Thanks, Jan
