BIOSDATE()
 Determines the system BIOS date
------------------------------------------------------------------------------
 Syntax

     BIOSDATE() --> dBIOSdate

 Returns

     BIOSDATE() returns the ROM BIOS date.

 Description

     As a rule, all industry-standard PC's insert a generated date at a
     particular memory location in the BIOS.  Based on this date,
     incompatibilities known to exist up to a particular release can be
     acknowledged.  The function returns a date-type value and spares you an
     elaborate PEEK.

 Note

     .  Although unlikely, you may not find a date at this BIOS
        position.  Therefore, you should test to see if a date is returned.

 Example

     Is this an older computer?

     IF BIOSDATE() < CTOD("01/01/85")
        ? "Older version ...!"
     ENDIF
