Abstract
APL, an interpretive processor, cooperates with external routines by calling those external routines to process data passed to them and receives results from the external routines. The called external routines, during their respective execution of the call, can request internal services of the calling APL interpretive processor. Such requests include execution of internal APL functions or operators, calling other external routines, recursive execution of external routines, and setting or obtaining values of internal APL data items.
