Thank you. here's the code i posted for the original request. using the transfer buffer works fine: /* * 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.
