ZDEBB-Display Blocked Tapes Online

Use this command to display blocked tapes online. You can:

A blocked tape is a tape of physical records that can consist of one or more contiguous logical records or parts of logical records. Physically, the blocked tape is read one record at a time; logically, the TPF system manages the blocked tape record by record.

Requirements and Restrictions

Format




RU
rewinds and unloads the blocked tape. If this is not done, the DBL tape will remain mounted.

RW
rewinds the blocked tape.

SF
shifts the blocked tape forward one or more logical records.

TD
performs a tape block hexadecimal dump of the next logical record.

TP
prints the next logical record in character format.

BB
shifts the blocked tape backward the specified number of physical blocks.

blocks
is the number of physical blocks from 0000-9999.

FD
shifts the blocked tape forward the specified number of logical records and performs a tape block hexadecimal dump (SR and TD).

FP
shifts the blocked tape forward the specified number of logical records and prints the tape block in character format (SR and TP).

RD
shifts the blocked tape backward the specified number of logical records and performs a tape block hexadecimal dump (BB and TD).

RP
shifts the blocked tape backward the specified number of logical records and prints the tape block in character format (BB and TP).

SR
shifts the blocked tape forward the specified number of logical records.

records
is the number of logical records from 0000-9999.

SD
searches the blocked tape for the specified data and performs a tape block hexadecimal dump (TS and TD).

SP
searches the blocked tape for the specified data and prints the tape block in character format (TS and TP).

TS
searches the blocked tape for the specified data.

displacement
is the 3-byte hexadecimal displacement in the logical record.

C
indicates that the data is character data.

X
indicates that the data is hexadecimal data.

-data-
is the character or hexadecimal data.
Note:
You must begin and end the data with the - character.
