(Fixes to pdfTeX can then propagate to the other engine(s).) | | Here's a minimal example: | | \def\a{\ifincsname T \else F \fi} | \expandafter\string\csname | 1\a | \expandafter\string\csname2\a\endcsname | 3\a | \endcsname | | #1 and #2 are "true" but #3 is "false". It seems like the first \endcsname has reset the "am i in a csname" switch rather than popped it back to its previous value. | | Cheers, | -- Will `--------` ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=4314&group_id=106
