delphi – Is it possible to define {$IFDEF} for more than one directive at once? – Stack Overflow

[WayBack] delphi – Is it possible to define {$IFDEF} for more than one directive at once? – Stack Overflow:

• use the {$IF Defined(xxx)} directive which allows boolean expressions like:
  • {$IF Defined(xxx) OR Defined(yyy)}
  • {$IF Defined(xxx) AND Defined(yyy)}
  • {$IF NOT Defined(zzz)}
• it has been in Delphi since Delphi 6 (see [WayBack] conditional statements – Why {$IFDEF MSWINDOWS} is replaced with {$IF defined(MSWINDOWS)} in Delphi XE5? – Stack Overflow and many other references).
• [WayBack] IF directive (Delphi)
  

  Type	Conditional compilation
  Syntax	{$IF expression}

  Compiles the Delphi source code that follows it if expression is true. expression must conform to Delphi syntax and return a Boolean value; it may contain declared constants, constant expressions, and the functions Defined and Declared.
