Set a scalar value from a parameter values,

GAMS

Hi,
I try to set a scalar value from a parameters value. I got an error message about uncontrolled set. Could anyone help me please?

sets
SE /s1*s4/
;
parameters
scenDone(SE)
/s1 0
s2 1
s3 0
s4 0/
;
scalar
temp1
/0/
;
temp1 = scenDone(SE) $ (ord(SE) eq 2);

Hi Omid



You should either write something like:

Temp1 = scenDOne(“s2”)

Or use a loop:

Loop(SE$$ (ord(SE) eq 2),

Temp1 = scenDone(SE);

);



Cheers

Thank you for your suggestion. I found another way,
temp1 = sum (SE $ (ord(SE) eq 2, scenDone(SE));
Thanks,
