CICS Considerations

For CICS applications, Micro Focus strongly recommends that you avoid all PL/I I/O (such as READ, WRITE, etc...) and storage allocation (ALLOCATE and FREE) features, and use solely the facilities provided by CICS via EXEC CICS statements. This guideline does not apply to CICS batch programs (running under JCL) using the EXCI interface to communicate from the batch program to programs running under CICS.
