When using CALL ABSOLUTE in a Microsoft BASIC program, the error
message "Argument Count Mismatch" occurs if parameters are passed to
the CALLed routine and the DECLARE for CALL ABSOLUTE in QB.BI is not
changed.

This information applies to Microsoft QuickBASIC Versions 4.00, 4.00b,
and 4.50 for MS-DOS, to Microsoft BASIC Compiler Versions 6.00 and
6.00b for MS-DOS, and to Microsoft BASIC PDS Version 7.00 for MS-DOS.

The following lines appear in the include file QB.BI shipped with
QuickBASIC Versions 4.00, 4.00b, and 4.50 and Microsoft BASIC Compiler
Versions 6.00 and 6.00b, and in QBX.BI shipped with Microsoft BASIC
PDS Version 7.00:

   'Call a routine at an absolute address.
   'NOTE: If the routine called takes parameters, then they will have to
   '      be added to this declare statement before the parameter given.
   DECLARE SUB ABSOLUTE (address AS INTEGER)

This DECLARE statement must be changed if any parameters are passed to
the CALLed routine. For example, if the CALLed routine was passed two
parameters as follows

   CALL ABSOLUTE(FirstNumber!, SecondNumber%, VARPTR(AsmProg(1)))

then the DECLARE statement in QB.BI or QBX.BI should be changed to the
following:

   DECLARE SUB ABSOLUTE(A AS SINGLE, B AS INTEGER, address AS INTEGER)
