See, for example, the model examples/bpp.mod, where parameter z is

Hello Andrew,

I see the point for indexed parameters (or sets) with bpp.mod. My solution is only valid for non indexed parameters and arrays.

How about the following solution: When evaluating an element of a parameter GLPK "earmarks" it as being in evaluation. If the same element of the parameter is reached recursively an error message "infinite recursion" is issued.

Best regards
