Did you place it after the “solve” statement?

Why doesn’t this statement work in the Shortest Path Problem example (spp.mod).

 

printf{(i,j) in E}"%11s\n", x[i,j];

 

I placed it after the minimize statement.  Here is the error message..

 

Reading model section from spp.mod...

spp.mod:39: only numeric, symbolic, or logical _expression_ allowed

Context:  [ i , j ] ; printf { ( i , j ) in E } '...' , x [ i , j ] ;

MathProg model processing error

 

 

I’m just trying to get the stdout results of the model.
