Is this what you are looking for? (z/OS Version 1.4 JCL User's Guide):
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea2b520/4.6.2.1.8?SHELF=EZ2ZO110&DT=20030819153510&CASE=
4.6.2.1.8 Disposition Processing of Data Sets that Do Not Exist
When you code a status subparameter of OLD, SHR, or MOD on a DD statement
for a data set that does not exist, processing proceeds based on whether you
have supplied VOLUME and UNIT information on the DD statement.
etc. etc.
That's part of it. What's more interesting, and which I still
can't find is any description of how failure allocating any one
data set affects allocation of other data sets.
And there's at least one error of fact there:
When VOLUME and UNIT Are Coded: When you code VOLUME and UNIT
on the DD statement, a JCL error will occur if the problem program
attempts to open the data set.
In fact, what I observe is "IEC143I 213-04,...". I believe a
system ABEND is not synonymous with a JCL error.
<My $0.02 comment:>
Do want to find things documented or any logic ?
Maybe it is documented somewhere, but no doubt, there is no logic here.
It's JCL. <g>
