Abstract
A method, apparatus, and program storage device for supporting improved record processing protocols for COBOL SORT and MERGE functions using input and output procedures in an object program. The SORT and MERGE functions include protocols for obtaining all of the input records via an input procedure in the object program and storing them into a memory area before performing the sort or merge steps of the SORT or MERGE function. Similarly, the SORT and MERGE functions store their results into a memory area before invoking the output procedure in the object program. Also, the present invention provides an optional overflow file which is used if the memory capacity is inadequate to store and retrieve all of the requisite data.
