Hi, this could actually be a question for the user instead of the devel list, but since it is a pretty recent feature, I'll ask here -- maybe we even have discussed this before. How does it work to specify instruments in a multi-equ system that is specified at runtime, with the 'equations' (plural) apparatus? The list-of-lists on the RHS already contains semicolons, which would seem to conflict with the semicolons normally used for specifiying instruments. thanks, sven
