KB#00111-DOS return codes are not valid

Title:

DOS return codes are not valid

Description:

The return code from an SCALL is always 0, regardless of the success of the operation. 

This behavior may or may not exist with any particular version of BBx. A programmer who is interested in writing 'portable' code should not rely on this to work consistently. BBx is given varying amounts of information from the operating system and the DOS libraries. MS-DOS has failed to report a return codes under some versions of the operating system.
