Dynamic sets in loop

GAMS
1

I am trying to update the set I am looping over at each iteration, my code looks like the following:

SET
hours / 1*8760 /;

Alias(hours, h);

SET
k(h);

SCALARS start, i;
start = 1;

for(i=1 to 365,

*----- Updating Set --------------------------------------

k(h)$((ord(h)>=i*start) and (ord(h)=1) and (ord(h)<20))=yes;
**** $188

188 Assigning to this set is NOT allowed. The set may have been
used in a domain definition or is a predefined/readonly set.

Anybody have any clues on what I am doing wrong?

Hello,

did you probably define ps as ps(w,k) instead of ps(w,h). if you use a set in a parameter definition it can not be dynamic!
