IBMBBCK*

IBMBBCK is a routine that concatenates character strings. The module has two functions at entry points:

IBMBBCKA: Concatenates two character strings into a target field.

IBMBBCKB: Implements the PL/I built-in function, REPEAT. REPEAT concatenates a single character string with itself a specified number of times and returns the resulting string.
