SAS(R) 9.1.3 Companion for z/OS

328 PDSCOPY Procedure Chapter 16
3 If output is in tape (sequential) format on disk (that is, when the OUTTAPE
option is used), the default is either the device track size or 32,760,
whichever is less.
3 If output is to disk, the default depends on the device type. However, it is
never greater than 18K unless you use the MAXBLOCK= option (see
MAXBLOCK on page 328). In addition, the default cannot exceed the device
track size or 32,760, whichever is less.
3 Unless the NODCBS option (described later) is specified and the output data
set is a partitioned data set on disk, the default value is reduced to the data
set control block (DSCB) block size of the partitioned data set, if that is
smaller.
For tape (sequential) format output, the specified block size cannot be less than
1.125 times the maximum input device block size, nor greater than 32,760. For
disk output, the specified block size cannot be less than 1,024.
DC
specifies that load modules that are marked downward compatible (that is,
modules that can be processed by linkage editors that were used before z/OS) are
eligible for processing. After they are copied by PROC PDSCOPY, the load
modules are not marked DC in their directory entry because PROC PDSCOPY
does not produce downward compatible load modules nor does it preserve their
attributes. If you do not specify the DC option and you attempt to copy load
modules marked DC, PROC PDSCOPY issues an error message.
DCBS | NODCBS
tells SAS whether to preserve the data control block (DCB) characteristics of the
output partitioned data set on disk. If NODCBS is specified, the data control block
(DCB) characteristics of the output partitioned data set on disk can be overridden.
The default value is DCBS.
If the NODCBS option is specified, PROC PDSCOPY changes the DSCB (data
set control block) block size of the output partitioned data set to the maximum
permissible block size for the device. Otherwise, the maximum permissible value
of the BLKSIZE= option is the current block size value from the DSCB, and the
DSCB block size is not changed.
Using the NODCBS option may enable PROC PDSCOPY to block output load
modules more efficiently. However, changing the DSCB block size could cause
problems when the data set is moved, copied, or backed up by a program other
than PROC PDSCOPY, particularly if your installation has more than one type of
disk drive. Consult your systems staff before specifying NODCBS.
INTAPE
specifies that the INDD= library is in tape (sequential) format. The INTAPE
option is assumed if a tape drive is allocated to the input data set.
MAXBLOCK=block-size | MAXBLK=block-size
enables you to override the limitation of 18K on the block size of text records in
the output library. (The value of BLKSIZE must be greater than or equal to the
value of MAXBLOCK in order to get text records at MAXBLOCK size.) If the
value of MAXBLOCK is not specified, then the maximum block size for text
records is 18K; this is the largest text block that can be handled by the FETCH
program in many operating environments. You can specify a block size greater
than 18K for text records, but doing so may cause copied modules to ABEND with
an ABEND code of 0C4 or 106-E when they are executed. You should use this
parameter only if you are sure that your operating environment (or TP monitor)
FETCH program supports text blocks that are larger than 18K. CICS and z/OS
FETCH programs, for example, support text blocks that are larger than 18K.
