Tape File Management Utilities
With the advent of HDR2 labels being maintained, the HDR2 could contain
information inconsistent with the actual tape contents. Without MODON 10
activated (OFF), TDYNCOPY issues message CADT572E and cancels. With
MODON 10 activated (ON), CADT572W is issued as a warning only message.
Optional Functions
// UPSI Setting Meaning
The optional functions are indicated by // UPSI statements. You can use any
combination of UPSI settings, except for // UPSI x1xx1xxx (48).
UPSI 1xxxxxxx
Multiple input files.
This bit prevents the tape from being rewound at OPEN or CLOSE (unless the
TLBL option is present to force a REWIND or UNLOAD). Therefore, either
multiple single-file volumes or multifile volumes can be processed. The last
input file is unloaded at CLOSE, however, unless the TLBL option overrides it.
UPSI x1xxxxxx
Multifile volume output.
This bit causes the output files to be written to the same volume (or multiple
volumes, if the files are controlled by CA Dynam/T).
UPSI xx1xxxxx
Unlabeled input.
Use this setting if the input is an unlabeled tape.
UPSI xxx1xxxx
Unlabeled output.
Use this setting if the output is an unlabeled tape.
UPSI xxxx1xxx
Stack output (only one output file).
The stack bit concatenates all input files as one output file. This is similar to a
merge function. The absence of this bit causes each input file to be copied as a
separate output file.
UPSI xxxxx1xx
Reblock file.
This function causes TDYNCOPY to request the logical record size and new
blocking factor from the console. If either the stacking or reblocking function is
being used, all checkpoint records from the input files are bypassed and a
console message is issued. Only one set of reblocking parameters is accepted.
