Example 1: Deactivation of critical resource with OVERRIDE specified

The operator enters a command string:
```
V NET,INACT,ID=CRITICAL,OVERRIDE=YES
```
VTAM® sends a pointer to the converted command string:
```
VARY INACT,ID=CRITICAL,OVERRIDE=YES
```
and a pointer to the command string length field (35) to the command verification exit.
In this example, CRITICAL is in a table of critical nodes contained in the exit. Therefore, the exit checks for the OVERRIDE option and removes the option from the command string.
The exit returns a pointer to the modified command string:
```
VARY INACT,ID=CRITICAL
```
and a pointer to a command verification return code of 0 to VTAM.
