T-BCK Command

Use T-BCK to backspace a specified number of tape records on a tape or to backspace to a previous End-Of-File mark.

Format

Parameter(s)

record

Number of tape records you want to backspace. The maximum is 32,767. If a number is not specified, T-BCK backspaces to the previous End-Of-File mark or to the load point.

Description

If an End-Of-File mark is encountered before the specified number of records are backspaced over, or if record is not specified, the tape is positioned before the End-Of-File mark. A T-FWD must be issued to position the tape after the End-Of-File mark before reading the next record.

NOTE

T-BCK is not supported on 1/4-inch tape drives.
