Check the -substr()- function :
From the help file (functions/string functions) :
substr(s,n1,n2) returns the substring of s starting at n1 for a length
of n2. If n1<0, the starting position is interpreted as distance from
the end of the string. If n2 is missing (.), the remaining portion of
the string is returned.
you might have to -tostring- the -destring- the variables.
Best,
Antoine
