### Resource Compiler - #elif Directive (OS/2)

Syntax

>     #elif constant-expression

The elif directive marks an optional clause of a conditional-compilation block defined by a ifdef, ifndef, or if directive. The directive controls conditional compilation of the resource file by checking the specified constant expression. If the constant expression is nonzero, elif directs the compiler to continue processing statements up to the next endif, else, or elif directive and then skip to the statement after endif. If the constant expression is zero, elif directs the compiler to skip to the next endif, else, or elif directive. You can use any number of elif directives in a conditional block.

constant-expression | Specifies the expression to be checked. This value is a defined name, an integer constant, or an expression consisting of names, integers, and arithmetic and relational operators.

Example
In this example, elif directs the compiler to process the second BITMAP statement only if the value assigned to the name "Version" is less than 7. The elif directive itself is processed only if Version is greater than or equal to 3.

>     #if Version < 3
>     BITMAP 1 errbox.bmp
>     #elif Version < 7
>     BITMAP 1 userbox.bmp
>     #endif
