Sorting with BIM-EPIC
Introduction
This section describes the considerations necessary to use BIM-EPIC controlled datasets with
all sort programs in general and these three sort programs specifically:
•
SYNCSORT using BIM-EPIC Interface
•
IBM SORT beginning with DFSORT 3.3
• CA-SORT
All sort programs check the assignment of a particular logical unit (SYSnnn) number before
actually opening a particular file (known as pre-open checking) and use PIOCS (Physical
Input Output Control Systems) to open, close, read, and write their datasets. Therefore, some
special considerations may be necessary when accessing BIM-EPIC controlled datasets with
your sort program. These considerations fall into three categories:
• Satisfaction of pre-open checking
•
Acquisition of necessary DTF information
• Deletion of the SORTWK dataset(s)
Pre-open checking can be satisfied using JCL considerations. BIM-EPIC automatically
deletes controlled SORTWK datasets at EOJ. DTF information not supplied by the sort
program either is lost or must be acquired by other means.
