Parameter description for PROCLIB

xxxxxxxx

Specifies the 1-8 character PROCLIB DD name being defined. DD names of the form PROCxx can be referenced by the JOBCLASS PROCLIB= statement. DD names of any format can be referenced on the JECL /*JOBPARM PROCLIB=ddname statement. If this name matches a DD name in the JES2 start PROC, then this PROCLIB concatenation will be used instead of the one in the JES2 start PROC.

Start of change If the PROCLIB DD name matches a static PROCLIB DD name from the JES2 PROC, the PROCLIB statement will logically alter the existing static PROCLIB, not replace it. End of change

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.

DD(nnn)=

Specifies up to 255 data sets to be concatenated to this PROCLIB DD name. Data sets in this list are compacted after each initialization statement is processed. If you specify DD(1), DD(20), and DD(100) for a new PROCLIB concatenation, the resulting concatenation will be renamed to DD(1), DD(2,) and DD(3). If you then set the data set name for DD(2) to null, JES2 will remove it from the concatenation leaving just DD(1) and DD(2) where DD(2) has the old DD(3) data set specification. Though up to 255 data sets can be specified, MVS™ rules limit any data set concatenation to 255 extents. If any data set has more than one extent, then the total number of data sets that can be supported will be reduced.

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.

DSName=jxxx...x

Specifies a 1-44 character data set name which JES2 will include in this PROCLIB concatenation. This data set must be a partitioned data set (PDS). If this value is coded as null (no operand specified), then the DD(nnn) will be deleted from an existing concatenation.

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.

UNIT=hhhh|/hhhh|nnnn|cccccccc

If the PROCLIB data set to be used is not cataloged, then you must specify the unit information for the device containing the data set in one of the following ways:

hhhh | /hhhh

specifies a 3 or 4 digit hexadecimal device number. Device numbers can be specified in one of the following formats:

UNIT=hhh
UNIT=/hhh
UNIT=/hhhh

where hhh and hhhh represent the device numbers. A slash (/) must precede a 4 digit device number.

nnnn

Specifies a device name.

cccccccc

Specifies a 1-8 character group name assigned to the device or group of devices that contained the non-cataloged initialization data set to be included.

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.

VOLser=xxxxxx

If the PROCLIB data set to be used is not cataloged, then this specifies a 1-6 character volume serial number on which the data set resides.

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.

UNCONDitional|CONDitional

Specifies what action JES2 should take if one of the data sets cannot be allocated. If CONDitional is specified (or defaulted) then if any data set cannot be allocated, the entire statement fails. The system will go into console mode to allow the operator to correct the statement. If UNCONDitional is specified, then an error allocating a single data set is ignored. The data set is not added to the concatenation but it remains assigned to the DD(nnn). If the concatenation is displayed, failed DD(nnn) will display the text 'ALLOCATION FAILED' before the data set name. If all the data sets in a concatenation fail to allocate, then the statement fails regardless of whether UNCONDitional was specified.

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.

NAME=xxxxxxxx

Intended mostly for $T command, NAME= allows the name of a PROCLIB concatenation to be changed. For example, specifying PROClib(TEST01) NAME=PROC01 renames the TEST01 PROCLIB concatenation to PROC01.

Modification: $T PROCLIB(xxxxxxxx) command, warm start or hot start.
