# u61a2 user exit

User exit u61a2 toggles a system-level
flag that controls visible output to the users terminal. When terminal
output is suppressed, this is equivalent to the ph PROC command. The reverse of this operation would be the u3193 user exit that sets terminal output on regardless
of its current setting.

## Example(s)

```
pq
u61a2
hsselect md
ston
hsave-list mx<
ston
p
u61a2
```
