Rational Developer for System z
Enterprise PL/I for z/OS, Version 4.1, Programming Guide

Using MSGFILE(SYSPRINT)

Any file attributes that are specified in the ENVIRONMENT option of the file declaration for SYSPRINT STREAM PRINT are ignored.

Any attributes that are specified on the OPEN statement for SYSPRINT are ignored.

When you use the OPEN statement to open the PL/I SYSPRINT STREAM PRINT file, the file is marked as opened in the PL/I control blocks, but it is actually opened by the Language Environment.

When you use the CLOSE statements to close the PL/I SYSPRINT STREAM PRINT file, the file is marked as closed in the PL/I control blocks, but Language Environment still keeps it open.

The synchronization between the Language Environment messages and PL/I user-specified output is not provided, so the order of the output is unpredictable.

The use of MSGFILE(SYSPRINT) restricts the line size specified by the LINESIZE option to a maximum of 225 characters.
