This RFE is not for "//SYSOUT DD ...".
This RFE is for "//MYFILE DD SYOUT=..."
BPXWDYN called by Cobol can do it. Why Cobol can't do it natively ?
Denis
This has been investigated further.
The COBOL runtime does not manage the DD SYSOUT. So there is no way for the COBOL runtime to allocate it.
By the time the Job step is running and the COBOL program is initialized; SYSOUT is already allocated.
As a result, this RFE is being rejected.
PS : look at sample program in attachments; it use FD and OPEN, WRITE, CLOSE statements. What we expect is to replace call to BPXWDYN for file allocation by full Cobol solution.
Hi,
Note: the request related to the dynamic allocation of file with a release in sysout (//MYDD DD SYSOUT = *), and not the allocation of the ddname SYSOUT (//SYSOUT DD...).
The purpose is to produce reports, using statments "WRITE AFTER ADVANCING n LINES / PAGE" to control the layout, and incidentally the "AT-END-OF-PAGE" clause or FD entry clause (LINAGE).
Using the DISPLAY statement will not allow the same control of the layout, except to expand it with the same possibilities as the statement WRITE concerning the management of the jumps lines and pages.
Incidentally, we use a code generator (IBM VisualAge Pacbase today, Rational Programming Patterns in future) to produce programs in genral, and reports in particular. The generated code uses the WRITE statement.
Kind regards,
Denis FALLAI
SYSOUT is managed by the system before initialization of COBOL (the user program and the COBOL library). It cannot be dynamically allocated. Since SYSOUT is being used in DISPLAY, we are investigating an alternative: To allow DISPLAY to send output to a user DD, which can be dynamically allocated. The name of this DD cannot be SYSOUT. Would this alternate approach satisfy your requirement ?
This RFE requires some more time to be considered.
