```pascal
|

|

#t_Address := #InVar; // Open the ANY pointer so we can work
|

Esempio di chiamata:
|
||
|
|
```pascal
|
||
|
|
CALL "FC Any To Dint on Alarm"
|
||
|
|
Address :="DB Pack Alarm".A471_39_4
|
||
|
|
Num_Alarm :=#T_Warning_Zone
|
||
|
|
```
|
||
|
|
|
||
|
|
Se questo bit `"DB Pack Alarm".A471_39_4` e true ritorna 471394 su `#T_Warning_Zone`
