#if
Preprocessor conditional directive
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.
Syntax
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
#if (DEBUG_LEVEL >= 2)
' This line is not compiled since the expression is False
Print "Starting application"
#endif
