Chapter 13: DYNCOPY−CA Dynam File
Utility Program
The CA Dynam file-copy facility, DYNCOPY, gives you a simple way to copy
files within CA Dynam. The program will copy any tape file or sequential disk
file to another tape or disk: tape-to-tape, tape-to-disk, disk-to-tape, or
disk-to-disk. The program also lets you specify reblocking of the output file
and provides facilities for selective copying of specified records from a file.
DYNCOPY uses standard LIOCS access methods so that input and output data
sets can be completely controlled by CA Dynam.
The second main function of DYNCOPY is to simplify file-dumping. All or
selected records of a file can be displayed in either hex-and-character format
or character-only format.
Input and output tapes may be labeled or unlabeled, and may contain
undefined, spanned, fixed-length, or variable-length records. Records may be
blocked or unblocked.
Parameters are supplied to support both CA System/Manager's SPUTIL
program and the CA EPIC TSIDDTD and TSIDDMP programs. All corresponding
parameters are interchangeable except where noted.
Operation
The following criteria must be met for the successful operation of DYNCOPY:
• DYNCOPY requires 64K + 8 bytes of partition GETVIS storage for the input
file buffer. When the COPY function is used, an additional 64K bytes of
partition GETVIS storage is required.
• The maximum block size supported is 64K.
• Tapes will be rewound at OPEN and at CLOSE, unless this positioning is
overridden by the use of the RUN, NOREW, RUNIN, or NOREWOUT
parameters on the DYNCOPY control statements or equivalent CA Dynam/T
TLBL options.
• The following file names (DTFnames) are required on DLBLs and TLBLs:
INPUT
TAPEIN
DISKIN
OUTPUT
Input disk or tape files
Standard-labeled input tapes
Input disk file
Output disk or tape files
