I didn't explain= myself fully. When writing the data file gschem would take any script attri= butes and write the value as an additional attribute, so the object would ha= ve:

script=3D"<att= ribute>=3D<expression>"

The second would be evaluated on a subsequent load and the former w= ould preserve the source expression, particularly if visible serving to docu= ment how the value was calculated. This would require no additional GUI supp= ort from gschem.
