The building block (along with V121) upon which V119 is based. Neither V120 nor V121 will be discussed in great depth here as they are cumbersome to use. Further information on these verbs can be gained by contacting Sprezzatura direct. (The routines execute at approximately twice the speed of V119 after initial setup is complete). V120 performs the "L" functionality of V119. That is to say, given a list of data elements @RM delimited with associated keys, @FM delimited, it returns just the keys @RM delimited. The length of each array element must be the same, and passed to the routine along with the data elements. For example if A contained "AAA" : @FM : "001" : @RM : "AAA" : @FM : "002" : @RM, then each element of the array would be considered as 8 characters long. Calling V120(A,8) would return 001: @RM : 002.
