CA Dynam for VSE User Guide

Parameters
LRECL=n
BLKSIZE=n
Specifies the logical record length in bytes. For variable-length records, specify
LRECL=V. This parameter is required for selective file copying and selective
printing.
Specifies the block size of the input files, in bytes, and must be a valid size for
the output device type. For variable-length blocked files, specify the maximum
size for the largest block in the file. Block size must be a multiple of the value
specified in the LRECL= parameter.
If the block size of the output file is to be different from the block size of the
input file, then the BLKSIZE= parameter must specify the block size of the
input file and either the BLKSZ= parameter on the DLBL or TLBL, or the
DYNCOPY OBLKSIZE parameter must be used to specify the block size of the
output file.
OBLKSIZE=n
Specifies the block size of the output file, in bytes, and must be a valid size for
the output device type. For variable length blocked files, specify the maximum
size for the largest block in the file. For disk output, do not add 8 to the
OBLKSIZE= value; simply specify the block size. Block size must be a multiple
of the value specified in the LRECL= parameter.
If the block size of the output file is to be different from the block size of the
input file, then the BLKSIZE= parameter must specify the block size of the
input file and either the DYNCOPY OBLKSIZE= or the BLKSZ= parameter on
the DLBL or TLBL must be used to specify the block size of the output file.
CISIZE=n
FILES= | INPUT=
RUN | RUNIN
Specifies the CISIZE, in bytes, to be used for output files on FBA devices, and
is only used when COPY is specified and reblocking is not to be performed.
This parameter is ignored if the input is on a CKD device. In this case, the
CISIZE for the output file is based on the track capacity of the input CKD
device. If the input file is on tape or on FBA and this parameter is not
specified, a CISIZE of 512 will be used. Do not specify this parameter if the
DYNCOPY BLKSIZE= parameter is also specified.
Specifies the number of input tape or disk files to be concatenated. If
concatenating disk files the DLBL for the first file must be DISKIN, and the
DLBLs for the second and subsequent files must be DISKINn, where n is a
number from 1 to 9. If concatenating tape files, the TLBL for the first file must
be TAPEIN and the TLBLs for the second and subsequent files must be
TAPEINn, where n is a number from 1 to 9. However, if the CA Dynam/T DROP
option is used on TLBLs, the same DTF name may be used for each file.
Specifies that all input and output tapes are to be rewound at open and
rewound and unloaded at close. If this parameter is not specified and the
NOREW or NOREWIN parameter is also not specified, the tape file(s) will be
rewound at open and close.
