IBMBANM*
IBMBANM processes the PL/I built-in function STRING. STRING concatenates independent data items into a single string.
IBMBANM has two functions at entry points:
IBMBANMA - calculates the length of the string that will result from concatenating all the elements passed to it.
IBMBANMB - concatenates all the elements of an argument structure or array into a target field and returns a single string.
