Usage

You cannot enter %If, %ElseIf, %Else, and %End If directly in the IDE. You must enter these directives in a file and insert the file in the IDE with the %Include directive.

productConst must appear on the same line as %If or %ElseIf. Nothing except a comment can appear on the same line following %If productConst or %ElseIf productConst, or on the same line with %Else or %End If. None of these lines can be continued with the underscore character (_).

To test each %If condition or %ElseIf condition in this statement, the LotusScript compiler calls the Lotus software application to evaluate the constant productConst. The product returns either TRUE (-1) or FALSE (0).

A condition is evaluated only if the product returns FALSE for the preceding condition. LotusScript compiles the statements for the first %If condition or %ElseIf condition that the product evaluates as TRUE. Once this happens, no further conditions are evaluated, and no further statements are compiled.

If neither the %If condition nor any %ElseIf condition evaluates to TRUE, the %Else statements (if any) are compiled.

You can include any number of %ElseIf directives in the block.

You can't include an %If block within an %If block.

LotusScript implements the constants in the following table as product #defines. When one of these is used as productConst, the LotusScript compiler does not call the product to evaluate productConst. LotusScript itself evaluates the constant as TRUE or FALSE. The value of each constant depends on the platform LotusScript is running on.
