Completely agree !!  but If I want to save the number like a string ( with in quotes) then how can we achieve it ?

I am trying to save / set the array from the class method.

I have tried the above mentioned code from the terminal but the char value of 0 is not triggered instead of null value its coming as char(0)

SAMPLES>set s1=111,s2=444
 
SAMPLES>set a(s2_$c(0),s1_$c(0))=77
 
SAMPLES>zw a
a("444"_$c(0),"111"_$c(0))=77
 
SAMPLES>
