Hello everyone,

Im not a big GAMS expert, so I’m having some difficulties trying to create a variable, i hope this isn’t too trivial. I know the bounds for the default are -inf to +inf and for the integer are 0 to +inf. However, for my model I require negative integer numbers as well. So basically the bounds of the default variable but only with integers. Does anyone know how to achieve this?

Many thanks in advance!
