Message Format

Most of the SYSTEM messages in the CRE are longer than those in the non-CRE

environment. If your CRE program is to process SYSTEM messages, make the record

area of the $RECEIVE file at least 256 characters long.

Message Replies

The replies to some messages have changed, particularly the replies to the messages

OPEN and CLOSE. In the non-CRE environment, you can reply to these messages

with anything; in the CRE, you must reply correctly or (in the Guardian environment)

operating environment error 2 results. For correct replies, see the Guardian User’s

Guide.

Arithmetic Overflow Processing

When an arithmetic overflow condition occurs that is not covered by ON SIZE ERROR,

the CRE traps the error. Then, if the program specifies PARAM INSPECT ON, the CRE

causes the program to enter the selected debugger (see Debugger Selection). If the

program specifies PARAM INSPECT OFF, the CRE causes the program to terminate

abnormally with a run-time diagnostic message and a trace to the offending statement.

TNS HP COBOL Programs in TNS User

Libraries

The CRE allows TNS HP COBOL programs in TNS user libraries if the programs

satisfy the criteria listed in Library Programs.

CHECKPOINT Access to Extended-Storage

Section

The CHECKPOINT statement can access Extended-Storage Section data items. For

the NMCOBOL compiler, the CHECKPOINT statement is available for the RVU D46.00

and G06.00 or later, software product revision T8107AAT (run-time library T8108AAR).
