#IF
Preprocessor conditional directive
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.
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.
Examples:
#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
