Functions 20, 22, and 23 Fail Under Basic Interpreter

ID: Q19868

The information in this article applies to:

Microsoft Mouse Driverfor MS-DOS, version 6.0

SUMMARY

Microsoft Basic Interpreter cannot use mouse driver version 6.0 functions 20, 22, or 23. These functions cause your program to hang.

To work around this problem, use the most current version of the mouse driver and/or a compiled version of Basic, such as QuickBasic.

MORE INFORMATION

This problem only applies to Microsoft QuickBasic if it is CALLing the driver. It is proper if QuickBasic uses the MOUSE.LIB utility, and so on (that is, goes to the driver through the INT code). The front end of the version 6.0 mouse driver, which allows a CALL rather than an INT to the driver, fails to handle the parameters for these calls correctly.

For more information on using CALL and INT with Basic Interpreter, query on the following words in the Microsoft Knowledge Base:

   DIRECT and CALL and DRIVER and ADDRESS
