The statements ERDEV and ERDEV$ give the run-time error message
"Advanced Feature Unavailable" when compiled and run in OS/2 protected
mode because these functions are set by DOS interrupt 24H, which is
not available in OS/2 protected mode.

ERDEV and ERDEV$ are not supported in OS/2 protected mode. This
restriction should be added to Page 40 of the "Microsoft BASIC
Compiler 6.0: User's Guide" for Versions 6.00 and 6.00b and to Page
520 of the "Microsoft BASIC 7.0: Programmer's Guide" for Microsoft
BASIC Professional Development System (PDS) Versions 7.00 and 7.10.

Code Example

I% = ERDEV
A$ = ERDEV$
