i realized what you meant later. here's a short program to show how to
do it. 

compile it using:

gcc apptitle.c -o apptitle.exe -Wall

and run it as:

apptitle title1 title2 title3 ... etc

and it displays all the command line arguments in the title bar.

/*
 * apptitle.c
 * routine to demonstrate how to change the title bar of the ms-dos  
 * window in windows 95
 * info taken from Ralph Brown's Interrupt List
 * INT 2F 168E - Windows95 - TITLE - SET APPLICATION TITLE
 *
 * by A. Sinan Unur

 * note that this code comes with absolutely no warranties of any kind.
 * try it at your own risk.
