With them you don't have to keep reinventing the wheel. But what if you have one library with some routines you like to use, and another library with other routines. Is there a way to use both libraries within the same program to take advantage of the routines in both libraries? The answer is Yes and No. You can if you combine the two libraries together to form one new library that contains both. Could you do the same thi...

First you will need QuickBasic. Then there are basically two ways. First you can use what is often referred to as a Third-Party Library. This is often the easiest way because there are many libraries available for downloading from local BBS systems. Some libraries are free, some are shareware and still others are public domain. The other method would be through the use of interrupts. Next month we ...

Although the primary focus is toward QuickBasic we do intend articles and programming examples that will also be applicable to QBasic. I have committed to putting out a September and October 1994 issue. Your response will determine if there should be continued issues past these dates. Depending on response we could continue monthly, or publish every other month. Minimal response woul...

Answer QBASIC is the interpreted version that has been included with all versions of MS-DOS since the release of version 5.0 If you still are not sure whether you have QBASIC or QuickBasic then do this: Start your QBasic or QuickBasic program. If the editor comes up with a screen in the middle that asks you if you want to run the Survival Guide then you have QBasic and not QuickBasic. Another way is to select the Help menu selection at the upper r...

These are INTERRUPT, INT86OLD, and ABSOLUTE. These routines provide for the use of software-interrupts. There are several types of interrupts, hardware interrupts and Software interrupts. But just what is an interrupt? An interrupt is a signal to the Central Processing Unit (CPU) to stop what ever it is doing, and process the interrupt. Information provided by processing an interrupt can return valuable information about so...

To get into the environment you will have to invoke ( start ) your QBasic or QuickBasic editor. Most QBasic users will find the QBasic interpreter program under the DOS directory. The QuickBasic compiler program is often under the directory QB45 ( But could be anywhere you put it ). To start QBasic simply type in QBasic and then press return. To start QuickBasic type in QB at the DOS prompt ( assuming you are under...

We keep track of values within a computer by assigning names to the values stored in the computer. For instance lets say we wanted to keep track of the number 5280 ( the number of feet in a mile ) somewhere in the computer. We could assign certain memory locations this value. In fact that is exactly what the computer does. But, it could get awfully complicated for the programmer if he had to keep track o...
