dimen 100.0pt not 100.0pt?
The I do not understand. I am testing if a dimension set can be checked against the expected value. It looks like 100.0pt is not really 100.0pt. Why? And how can I do this test properly with true as result? \scratchdimen=100pt\relax \iftok{\the\scratchdimen}{100.0pt}true\else false\fi  printing \the\scratchdimen results in 100.0pt while \meaning\scratchdimen results in: constant dimension 100.0pt yours sincerely dr.

It has to do with catcodes (of p and t) so you need this: \iftok{\the\scratchdimen}{\detokenize{100.0pt}}true\else false\fi But ... you should do it the way Wolfgang pointer out Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
