DLBL catdd identifies the VSAM catalog (defined by a previous DLBL
definition) which contains the entry for this data set.You must use the CAT option when the data set you are
creating or identifying is not cataloged in the current job
catalog. catdd is the ddname in the DLBL definition for
the catalog.BUFSP nnnnnn
specifies the number of bytes (in decimal) to beI/O buffers by VSAM data management during
execution, overriding theBUFSP value in the ACB file. The maximum value for nnnnnn is 999999;
commas are not permitted.

2. Toenter an OS or DOS file identification on the DLBL command line,
it must consist of 1-to 8-character qualifiers separated by
periods, with a maximum length of 44 characters, including periods.For example, the file TEST.INPUT.SOURCE.D could be identified as
follows:
dlbl ddl c dsn test input source d (options••• Or, it may be entered interactively, as follows:
dlbl ddl c dsn ? (optionsDMSDLB220R ENTER DATA SET NAME:
test.input.source.d
Note that when the data set name is entered interactively, the data
set name must be entered in its exact form; when entered on the
DLBL command line, the periods must be omitted.You must use the interactive form to enter a DOS file-id that
contains embedded blanks or hyphens.
3. InDJS/VS, a data set that has been defined as is opened
with an error code ofX· 11'. CMS supports the DUMMY operand of the
DLBL command in the same manner.OS users should not use the DUMMY operand in CMS, since a dummy data set does not return, on open, an
end-of-file indication.
