RouterOS Scripting

I want to store some values in comment field of each user in UM.
the plan is:

Input values to array and input array to comment field.
Output comment to array and output array to varialbles.

Is it possible in Mikrotik? if yes, can you me tell to do it?

for example string “a,b,c” can be converted to array of 3 elements a b c

{
 :global comment "a,b,c";
#convert to array
 :set comment [:toarray $com];
# print first element of the array
 :put [:pick $comment 0];
}
