T-CHK

Checks a tape for parity errors.

Command Class

TCL-I command.

Syntax

T-CHK {channel}

Syntax Elements

channel Optional. The channel to which the required tape units have been attached using the ASSIGN command. If omitted, the tape units attached to the default channel are used.

Comment

Before using T-CHK, you must attach the required tape units to the port.

Error checking continues until an EOF (end-of-file) mark is encountered.

To perform multiple T-CHKs on the default channel you can use the CHECK Proc.

Example

:T-CHK B

[94] END OF FILE

The tape assigned to channel B is checked for parity errors.
