Upgrading seems to have broken \startconstants (and probably also \startvariables). The code below worked in cont-tmf version 2008-08-05 but no longer in 2008-10-31: \startconstants all spine: spine % etcetera \stopconstants \startvariables all % etcetera \stopvariables The error is: ! Undefined control sequence. <argument> \c!spine =\v!none \xprocesscommaitem #1,#2->\if ,#1 ,\@EA \xprocesscommaitem \else \if ]#1\@EAE... <argument> ...=\v!cd ,\c!spine =\v!none ,\c!state =\v!draft ,\c! output =\v!p... \xdogetparameters #1]->\xprocesscommaitem #1 ,],\@relax@ l.162 ] Addition of "\def\c!spine{}" makes the error go away. So definitely something is broken in the latter release for the start- macro(s). Could there be given a quick fix sothat I can avoid reverting back to the earlier version or adding changes all ver the place? Hans van der Meer
