I stand corrected; I misread earlier in the same section:
Each directory or filename:
Is preceded by a slash (/). The system treats any consecutive slashes as a
single slash.
...
Has a length of 1 through 254 characters, not including the slash.
But now I've read it more carefully and submitted the RCF:
Hello, MHVRCFS
In:
Title: z/OS V1R13.0 MVS JCL Reference
Document Number: SA22-7597-15
12.48.2 Subparameter Definition
pathname
Is incomplete, perhaps misleading. The description
appears to prohibit the following which are in fact
allowed:
o A pathname need not contain a filename; it may consist
solely of directories, in which case it refers to a
directory.
o If (and only if) a pathname refers to a directory, it
may end with a slash.
The following may be implicit, or perhaps needs clarification:
o The list of directories may be empty; the path may consist
of only a filename, in which case it refers to a file in
the root directory; or of only a slash, in which case it
refers to the root directory itself.
The following appear to be permitted, but are in fact invalid:
o A slash may not appear in a directory or filename; it may
be used only as a separator between directories and the
filename.
o The forms "." and ".." may not be used as filenames; these
are reserved for directory names.
If all this is explicit in other IBM publications, it would be
better to shorten 12.48.2 and supply a cross-reference to
such publications.
Thanks,
