PROBLEM WITH 'CALL ABSOLUTE'

[varshney_sp]

Friends, I'm using quick basic 4.5 and I have a problem with running assembly procedures. Whenever I use CALL ABSOLUTE statements the compilers flags an error message "SUB PROGRAM NOT DEFINED".

The same program perfectly runs in the qbasic 1.1 compiler provided with MS-DOS 6.22

While going through the Online quick basic help I found instructions related to the use of CALL ABSOLUTE statement. According to it, qb should use qb.qlb as the default library ( and is using off course!) and I should properly link my program to the appropriate library, but I don't know how to link my program to libraries and also I don't know which library to link.

The problem remain same when I run the program in Quick Basic Extended which I downloaded from this site.

I'm new to basic programming :-[ please help.

Also tell me that does Quick Basic Extended version provided on this site is the same what is called Quick Basic 7.1 ( this compiler was listed under the name of Quick Basic 7.1)

You need to include the QB.BI file also. Copy the code from the bottom of this post, paste it into Notepad and save it in your QB directory as QB.BI.

Then at the beginning of your program, add this line.

Code: Select all

'$INCLUDE: 'QB.BI'

Code: Select all

::)Hello Dr_D

:DThanks for your response.

:-[ I tried what you said but the result is same, what to do now? Please tell me.

Can you post one of the lines that your using CALL ABSOLUTE on? Maybe it's just a simple syntax error...

One more thing...
Are you compiling from the command line or the IDE?

If your compiling from the IDE, will the program run without compiling?

The file works, but the forums added

Code: Select all

&nsbp;

to each of the lines, which is HTML for a user-defined space. Get rid of all those and follow his instructions. It should run correctly from there.

You've probably worked it out by now , but anyway I had a similar problem. The cause was I had not reset the seg offset. So putting DEF SEG = 0 after the CALL ABSOLUTE sorted the problem
