#ELSE

Parameters: NONE

Returns: NONE

      #ELSE is used in combination with the conditional #IF / #ENDIF directives. #ELSE allows the #IF directive to choose between two paths the compiler could take.

      #If performs a comparison of a constant expression at compile time, if the expression resolves to be true, the code following the #IF statement and between the #ELSE statements will be compiled. If not, then the code between the #ELSE-#ENDIF will be ignored.

      For more information on the logic behind #IF / #ELSE / #ENDIF statements, please refer to the #IF page.

FACTS:

* #IF/#ELSE/ #ENDIF are directive all evaluated at compile time.

Mini Tutorial:

This simple examples shows how to use th #IF/#ELSE/#ENDIF directives to conditional select a section of code to compile.

  Constant MyFlag = 100

; Compare the MYFLAG constant during compilation with 50. If
; the constant is greater than 50, then the compiler will include
; this code section.

; if not.. it will ignore those lines completely and compile the code
; between the #ELSE and #ENDIF.

  #IF  MyFlag > 50

     Print "Yes My Flag was bigger than 50"
     Print "Yippie"

  #ELSE
     Print "This Code will not be compiled"
     Print "as the #IF expresion above is TRUE"

  #ENDIF

This example would output.

  yes My Flag was bigger than 50
