Set Application Title

Sets the application title to the given string.

mov  ah, 16h           ; Windows multiplex function
mov  al, 8Eh           ; VM Title
mov  di, seg AppTitle  ; see below
mov  es, di
mov  di, offset AppTitle
mov  dx, 0             ; Set Application Title
int  2Fh
cmp   ax, 1
je   success

Parameters

AppTitle

Pointer to a null-terminated string specifying the application title. The title must not exceed 80 characters, including the terminating null character. If this parameter is zero or points to an empty string, the function removes the current application title.

Return Values

Returns 1 in the AX register if successful or zero otherwise.

Remarks

Although not common, Set Application Title can return 1 in the AX register even though the title was not changed. In general, applications must not rely on the operating system to keep an accurate copy of the current title.
