How to Execute TSR Program

Install Borland C++

• Download Borland C++ from LMS– http://vulms.vu.edu.pk/Courses/CS609/Downl

oads/BORLANDC.rar– Install as per instructions given in the tutorial– http://

vulms.vu.edu.pk/Courses/CS609/Downloads/How_to_Install_BolandC.ppt

Open Borland IDE

• Go to Bin folder inside BorlandC• Locate BC.exe• Double Click to open IDE

Note: IDE stands for Integrated development environment and it is named as because Editor, Compilor, Debuger, Linker etc. are all integrated in one environment.

This is the simple program given in handouts at page#29. I have saved it as TSRCAPS.C

Click on Compile menu then compile.

This is compilation report and it shows that our

program has no errors but one warning. We will

ignore that warning for now.

Press any key to close this report.

To generate .com file, open DOS Command prompt, Go to D: drive

and inside BORLANDC\BIN directory as shown in

this figure.

This is the Command to generate .com file.

There is a warning (again) but our TSRCAPS.com is

generated.

After command execution close this DOS window as you can

see on its title bar that cmd.exe is not running purely.

This is our TSRCAPS.COM file

located inside D:\BORLANDC\BIN

Open new instance of DOS Command prompt. Go to D: drive and inside

BORLANDC\BIN directory as shown in this

figure.

We have executed TSRCAPS.COM but our text is not appearing in Capital as it should be.

Again, open new instance of DOS Command prompt. Go to D: drive and inside

BORLANDC\BIN directory as shown in this figure.

Before executing TSRCAPS.com, just type edit to open edit program. This is done to do some

internal parameter setting in order to get access to some

internal resources.

Simply close edit program after opening it.

In order to execute, just type TSRCAPS.COM and press Enter.

Now you can see, I am unable to type in lower case…even by switching ON/OFF caps-lock key.

You see cmd.exe (DOS) is running along with TSRCAPS.com

The End
