This is the GPIB language interface for Microsoft QuickBASIC (version 4.0 or 4.5), a DOS programming environment for creating 16-bit applications. Download the Qbasic.zip file (in the example.zip file, below). This file contains the declaration file QBDECL.BAS, the language interface file QBIB.OBJ, and some sample programs.
How to Use the Microsoft QuickBASIC Language Interface:
The 16-bit GPIB language interface for Microsoft QuickBASIC contains the following files:
QBDECL.BAS: Microsoft BASIC program declarations QBIB.OBJ: Microsoft BASIC language interface object module
If you have the GPIB Software for DOS, the QuickBASIC language interface and the sample applications are located in the directory called \QBASIC (where is where the GPIB software for DOS is installed).
II. Items to Include in Your GPIB Application
You must include the following line at the beginning of your application:
Next you need to link in the QBIB.OBJ file to your application.
III.A. Compiling, Linking, and Running from the QuickBASIC Environment
Before you can run an application, called yourprog, from within the QuickBASIC interactive environment, follow the steps listed below:
1. From the DOS command line, create an object module library called QBIB.LIB, by typing in the following:
LIB QBIB.LIB + QBIB.OBJ;
2. From the DOS command line, to create a QuickLibrary called QBIB.LIB that is linked with the QBIB.OBJ language interface, type in:
LINK /Q QBIB.OBJ,,,BQLB40.LIB; (for QuickBASIC version 4.0)
LINK /Q QBIB.OBJ,,,BQLB45.LIB; (for QuickBASIC version 4.5)
NOTE: Please remember to include the three commas between QBIB.OBJ and the BQLB4x.LIB.
3. To invoke the QuickBASIC environment where you can run the application called yourprog, type the following on the DOS command line:
QB YOURPROG.BAS /L QBIB.QLB
III.B. Compiling, Linking, and Running from the DOS Command Line
To run an application, called yourprog, from the DOS command line, follow the steps listed below:
1. To compile the BASIC application, called yourprog, type in:
2. To link the BASIC application, called yourprog, with the QBIB.OBJ language interface, enter the following:
LINK YOURPROG.OBJ QBIB.OBJ;
3. To run the application, called yourprog, from the command line, type in:
