how can I get the difference between two parameters?

GAMS
1

i have two parameters:
1.A, {1,2,3,4,5,6,7,8,9,10}
2.B, {3,5,7,8}
C∈A and C∉B

i want to get a new parameter C which is {1,2,4,6,9,10}
C must be the parameter because I need to use C in the following calculation.
how can I do that in Gams?

Thank you

You question is posed in terms of Parameters, but your data and all other material indicate that you really are looking for a Set, and a Set that can change is in GAMS called a dynamic set. The GAMS users guide has a whole chapter on Dynamic Sets (chapter 12). Try to read it!
