# /of vs. /zW Compiler Switch to Build MS-DOS API Libraries

ID: Q103593

The information in this article applies to:

- Microsoft FoxPro Library Construction Kit version 2.5

Although the /of and /zW WATCOM compiler switches are documented as generating equivalent code, Microsoft has discovered instances where this is not the case. We recommend using /of instead of /zW when compiling MS-DOS API libraries.
