Relationship to other parameters

Code the PATHOPTS parameter only on a DD statement that contains a PATH parameter.

You can code the following parameters with the PATHOPTS parameter:

BLKSIZE
BUFNO
DSNTYPE=PIPE
DUMMY
FILEDATA
LRECL
NCP
PATH
PATHMODE
PATHOPTS
RECFM
TERM

If:

You specify either:
- OCREAT alone
  or:
- Both OCREAT and OEXCL
on the PATHOPTS parameter,
And if:
The file does not exist,

Then MVS™ performs an open() function. The options from PATHOPTS, the pathname from the PATH parameter, and the options from PATHMODE (if specified) are used in the open(). MVS uses the close() function to close the file before the application program receives control.

For status group options other than OCREAT and OEXCL, the description in this documentation assumes that the application passes the subparameters to the open() function without modification. That is, this application uses dynamic allocation information retrieval (the DYNALLOC macro) to retrieve the values specified for PATHOPTS and passes the values to the open() function. The application program can ignore or modify the information specified in the JCL.
