#if

FreeBASIC

#if
 
Preprocessor conditional directive

Syntax

#if (expression)
' Conditionally included statements
#endif

Description

Conditionally includes statements at compile time.

Statements contained within the #if / #endif block are included if expression evaluates to True (non-zero) and excluded (ignored) if expression evaluates to False (0).

This conditional directive differs from the If conditional statement in that #if is evaluated at compile-time and If is evaluated at run-time.

Example

#define DEBUG_LEVEL 1
#if (DEBUG_LEVEL >= 2)
  ' This line is not compiled since the expression is False
  Print "Starting application"
#endif
