Isset

The isset command returns the value of the specified flag.

Syntax

isset(flg fA)
fA

Remarks

Test commands are only valid in an if statement. The isset command returns TRUE if the flag is set, FALSE if it is not. You can use just the flag itself as an alternate syntax.

This statement can be combined with the NOT operator to create a ‘flag not set’ test.

Possible Errors

None.

Example

Code:

<syntaxhighlight lang="agi"> if(isset(f40))

 { 
 print("flag 40 is set (TRUE)");
 }

if(f40) [ alternate syntax

 {
 print("flag 40 is set (TRUE)");
 }

</syntaxhighlight>
