 How To Use Future Lib In Your

 Programs 

Important : To view this page correctly you require Papyrus font (You can download it here and add it to your c:\windows\fonts \ directory). Also I dont accept any liability/responsibility for any damage this page may cause you directly or indirectly.

Ok so you want to use Future Library in your program?

Its installation and usage is really simple!

Things that you require:

1. FL35.zip file (you can download it here from my site)

2.Qb45 or Qb71 depending on which compiler you want to use.

That's all!

Steps to follow:

First Step:

You need to locate your qbasic directory is and find out whether all the files are in the same directory. Some of the Zip files that you download from the internet contain all the files like EXEs, LIBs, QLBs in the same directory while some are in different directories like all my LIB files are under the directory c:\bc7\lib\. But my friend's LIB files are under the directory e:\qb71\.

Second Step:

 Unzip FL35.zip to a temporary folder like C:\Temp

Third Step:

Execute the flbuild.exe and you will see a screen in which there are only 2 menus, a file menu and a setup menu

Fourth  Step:

         First thing that you need to do is open the setup menu and click on the program option.

         Here you need to set the compiler path and the library path for either qb4.5/7.1 which ever you want to use. 

         If you want to build the library for qb 7.1then only enter the paths in the text boxes provided for qb7.1. Same rule applies for when you want to build the library for qb4.5. 

What is the compiler path?

Compiler path is basically where you have got the lib.exe and link.exe files under your QB directory. Locate any one of these files and you will know what is your compiler path.

What is the library path?

Library path is location where you have got the brt71efr.lib, qbxqlb.lib and qbx.lib files under your QB directory. Locate any one of these files and you will know what is your library path.

Set these paths accordingly. In my case they were:

         Compiler Path: c:\bc7\binb\ 

         Library Path: c:\bc7\lib\

After setting these paths click on OK button.

 

Fifth Step:

Now we have to determine the components you want in the library. For example I don't use the sound routines of Future Library so I simply don't include them.

You will ask - What is the use of removing those routines? 

Well my  answer would be the library size would reduce and when you compile your program into an EXE it would too be smaller in size.

To determine the components we want to include in the library click on the setup menu and then click on the library option and click on the components that you want to include in the library.

Note:  

The option SVGA Library contains sub functions which you can choose to remove. You can see them by clicking the '>>' button besides it (Which is next to the 'i' button).

Once you do that click on OK button at the bottom.

Sixth Step:

Ok! Now we are ready to build the library!

All you need to do is click on the 'Build qbasic 7.1 library' or 'Build qbasic 4.5 library' which ever you are building.

 

Errors you may get while building the Future Library:

         Any errors you get will be related only to the paths that you have set.

         If incase you get an error like "lib.exe not found" or "link.exe not found" then it means that you have set the compiler path incorrectly.

         If incase you get an error like "brt71efr.lib not found" or "qbxqlb.lib not found" or "qbx.lib not found" then it means that you have set the library path incorrectly.

Seveth Step:

So you have successfully built the library you need to copy the following files to your QB directory. You can find these files in the temporary directory which we created to unzip fl35.zip:

For qbasic 7.1(pds) compiler:

1. Future71.lib

2. Future71.qlb

3. Future.bi 

For qbasic 4.5 compiler:

1. Future45.lib

2. Future45.qlb

3. Future.bi 

Its important that you should not forget to copy any of these files! All three are very very important!

Eighth Step:

         Now we have to actually use these three files. So now open the ms-dos prompt in windows.

         Change your current working directory to your QB's directory and key in the following commands:

c: <enter>

cd bc7 <enter>

For qbasic 7.1:

qbx/ah/lc:\bc7\future71.qlb/es <enter>

For qbasic 4.5:

qb/ah/lc:\bc7\future45.qlb <enter>

 

Note: 

         The /es switch is very important for qbasic 7.1! 

         Also for both the compilers you must give the path where you have copied the files (future45/71.lib, future45/71.qlb, future.bi)

         In my case the path is c:\bc7\ it may vary for you.

         Also you cannot use the library built for qbasic 4.5 in qbasic 7.1 and vice versa.

In qbasic's ide you need to include the future.bi file like this:

'$include: 'future.bi'

Note: 

You need to sometimes include the path where the file is located like this (for example):

'$include: 'c:\bc7\future.bi'
