GAMS World Forum

Hi there,

I'm trying some alteration to the DICE2013 model. I define a set of a hundred values and want to access one value for each period t. I.e. if t=5, I want GAMS to return the fifth value in the parameter cereq.

sets t Time periods (5 years per period) / 1*100 /
cereq list of multipliers /v1*v100/

I tried:

cereq(t)$ord((cereq)=t)

but that causes the program to crash.

How do I have to do this?

Many thanks

You can compare the positions of the two elements in their respective sets by writing or compare the position of cereq with the value of t: Using .val is useful when comparing numerical sets that don't naturally start at 1, for example years.

Thank you!
