Hi Arash, Steffen,

Indeed, I have noticed the same issue myself. I believe that this kind
of term-by-term dimension checking was a feature of ASCEND in the Tcl/Tk
GUI days, but somewhere along the way, the feature hasn't been correctly
incorporated into the newer PyGTK GUI.

Ben, I you familiar with where the dimensional checking of equations
(declarative section) is done in ASCEND? Is there a function that needs
to be run to conduct this checking, that perhaps is outside the
'system_build' step, and maybe still embedded in the Tcl/Tk interface code?

There *is* dimension checking in the PyGTK GUI in relation to
variable-setting, in assignment statements within METHODs, but I think
that what you are referring to is missing and would be something that we
can restore.

Cheers
JP
