Hi Hans, looks my knowledge of TeX is holey like a Leerdammer. Can you tell me why you fire a warning for already defined, non-global allocated registers? Some of them make sense here but even a grouped (and local allocated) register gives such a warning. warning : \count \OLDpdfcompresslevel is already defined (\relax it first) \def\disablePDFcompression% {\bgroup % \let\OLDpdfcompresslevel\relax \newcount\OLDpdfcompresslevel \OLDpdfcompresslevel\pdfcompresslevel \pdfcompresslevel\zerocount\relax} \def\allowPDFcompression% {\pdfcompresslevel\OLDpdfcompresslevel\egroup} - Peter

Because it's nonsense what you do, just assign the value to your counter inside of the group and will be keeped local. \newcount\OLDpdfcompresslevel \def\disablePDFcompression {\bgroup \OLDpdfcompresslevel\pdfcompresslevel \pdfcompresslevel\zerocount\relax} \def\allowPDFcompression {\pdfcompresslevel\OLDpdfcompresslevel\egroup} Wolfgang

*guilty* in this point... and the past has show, that i'm a repeat offender ;)
\newcount\OLDpdfcompresslevel
\def\disablePDFcompression {\bgroup \OLDpdfcompresslevel\pdfcompresslevel \pdfcompresslevel\zerocount\relax}
\def\allowPDFcompression {\pdfcompresslevel\OLDpdfcompresslevel\egroup}

there are: \def\nopdfcompression {\pdfobjcompresslevel\zerocount \pdfcompresslevel\zerocount} \def\maximumpdfcompression{\pdfobjcompresslevel\plusone \pdfcompresslevel\plusnine } \def\normalpdfcompression {\pdfobjcompresslevel\plusone \pdfcompresslevel\plusthree} with \normalpdfcompression being default ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

warning : \count \OLDpdfcompresslevel is already defined (\relax it first)
\def\disablePDFcompression% {\bgroup % \let\OLDpdfcompresslevel\relax \newcount\OLDpdfcompresslevel \OLDpdfcompresslevel\pdfcompresslevel \pdfcompresslevel\zerocount\relax} \def\allowPDFcompression% {\pdfcompresslevel\OLDpdfcompresslevel\egroup}
first of all, there is a command \nopdfcompression so you don't need the hackery then, \newcount is global and the latest releases of context catch redefinitions so: - either move the \newcount outside the macro - or relax it first (which will spoil a counter then) (the whole allocator has been rewritten and is no longer doing it in the traditional tex way, at least not with respect to where things end up; cleaner this way) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

well, the code is messed up this way, because i had also disabled \pdfobjcompresslevel in a prior version. after i found out, that you can't change it at runtime (only once at the very beginning of the document) i removed it. the rest of the macro was unchanged.
then, \newcount is global and the latest releases of context catch redefinitions so:
- either move the \newcount outside the macro - or relax it first (which will spoil a counter then)
ok, will do so. thanks Hans and Wolfgang!
(the whole allocator has been rewritten and is no longer doing it in the traditional tex way, at least not with respect to where things end up; cleaner this way)

actually, i could probably make a global as well as a local registre pool (thr trick is in avoiding stack buildup) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
