SUMMARY
The statements ERDEV and ERDEV$ give the run-time error message &quot;Advanced Feature Unavailable&quot; when compiled and run in OS/2 protected mode because these functions are set by MS-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 &quot;Microsoft Basic Compiler 6.0: User's Guide&quot; for Versions 6.00 and 6.00b and to Page 520 of the &quot;Microsoft Basic 7.0: Programmer's Guide&quot; for Microsoft Basic Professional Development System (PDS) Versions 7.00 and 7.10.

Code Example
I% = ERDEV A$ = ERDEV$
