1.2.33 $IFOPT : Start conditional compilation

The {$IFOPT switch} will compile the text that follows it if the switch switch is currently in the specified state. If it isn’t in the specified state, then compilation continues after the corresponding {$ELSE} or {$ENDIF} directive.

As an example:

{$IFOPT M+}  
  Writeln (’Compiled with type information’);  
{$ENDIF}

Will compile the Writeln statement only if generation of type information is on.

Remark:The {$IFOPT} directive accepts only short options, i.e. {$IFOPT TYPEINFO} will not be accepted.
