Fix list and new features for Enterprise COBOL for z/OS

Product Documentation

Abstract

This document contains a complete listing of releases, refreshes and fix packs (also known as PTFs) sorted by version for IBM Enterprise COBOL 5.x/6.x for z/OS. The PTFs contain APAR fixes and new function APARs delivered as part of the continuous delivery process. We recommend installing the latest PTFs as they are cumulative (ie they contain all the APAR fixes made available for the product since it first shipped).

COBOL Runtime General Information:
LLA is designed to minimize disk I/O by keeping load modules in a VLF (virtual lookaside facility)
dataspace and keeping a version of the library directory in its own address space. If your site has
run dataset CEE.SCEERUN managed by the LLA facility, then refresh LLA/VLA each time after
you apply the COBOL run-time LE PTF.

Helpful Hints For Obtaining Technical Assistance:

Before contacting IBM Enterprise COBOL for z/OS Support, gather the background information that you need to describe the problem. When you describe a problem to an IBM software support specialist, be as specific as possible and include all relevant background information so that the specialist can help you solve the problem efficiently. To save time, know the answers to these questions:

Can you reproduce the problem? If so, what steps and compiler options do you use to reproduce it?
Can the issue be reduced to a small test case?
Can the test case be provided to IBM?
What compiler version and fix pack level were you using when the problem occurred?
Do you have logs, traces, or messages that are related to the problem?
Is there a workaround for the problem? If so, be prepared to describe the workaround.

If you have helpful information to diagnose or identify the problem on your system, you can provide this data by following the instructions to exchange information with IBM Technical Support .

Corrected in this PTF without an APAR:

NUMCHECK incorrectly flags an alphanumeric data item whose value is correct.

Relevant technote:

The NUMCHECK compiler option now validates the contents of an alphanumeric data item used as a sender to a numeric data item in a MOVE statement.

Compiler APAR Fixed:

APAR	Description

must also be applied on all systems where these programs are linked or run.

The NUMCHECK compiler option now generates an implicit numeric class test for each alphanumeric sender whose contents are being MOVEd to a numeric receiver. Prior to this PTF, alphanumeric senders were not checked. There was no APAR for this change, but the change is included in this PTF. Customers may see more NUMCHECK abends/messages due to this change and will need to correct their alphanumeric data so that it is truly numeric or add program logic to properly massage the invalid data.

Relevant technote:

The NUMCHECK compiler option now validates the contents of an alphanumeric data item used as a sender to a numeric data item in a MOVE statement.

Compiler APAR Fixed:

APAR	Description
PH27504	Compile failure IGYRC5108-U error Uncorrectable program interrupt condition (RC=16)

Corrected in this PTF without an APAR:

NUMCHECK incorrectly flags an alphanumeric data item whose value is correct.

Relevant technote:

The NUMCHECK compiler option now validates the contents of an alphanumeric data item used as a sender to a numeric data item in a MOVE statement.
