there is no command to perform an operation like this, but you can make one:
MAKELIST(when((L1(X)) = 1,2,L1(X)),X,1,SIZE(L1),1), here the list you want to change is stored in L1, with
L1:=MAKELIST(when((L1(X)) = 1,2,L1(X)),X,1,SIZE(L1),1)
you replace the actually stored list.

Your solution is also faster than my "for" loop. Thanks so much
