# CICS Trigger Queue Verify Task

`SXTV` reads HVT queues and verifies that the record headers are in proper sequence.

Any errors cause printed error messages on CICS `CEELOG` in either of the following forms:

- `"Queue:queue name Record: number - Length Invalid - Exp:number Got:number"`
- `"Queue:queue name Record: number - Number Invalid - Exp: number Got: number`"

Note: No data is changed or removed from the queues.
The following table describes the command-line parameters for `SXTV`.
