Problem with clear command

Hi All

I'm currently writing a very simple UNIX script to process some work. The very first thing I do on my script is use the "clear" command.

how my file looks...

clear
echo "Return status: $?"

For some strange reason, the return status being returned is 1, not 0 as i expected.

Has anyone ever encountered an anomaly like this before, or could there be some account permissions problem? It's very simple code, so basic that it's got me completely stumped!

Any help would be much appreciated.

clear(3XCURSES) 					  X/Open Curses Library Functions					   clear(3XCURSES)

NAME
clear, erase, wclear, werase - clear a window SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int clear(void); int erase(void); int wclear(WINDOW *win); int werase(WINDOW *win); DESCRIPTION
The clear() and erase() functions clear stdscr, destroying its previous contents. The wclear() and werase() functions perform the same action, but clear the window specified by win instead of stdscr. The clear() and wclear() functions also call the clearok() function. This function clears and redraws the entire screen on the next call to refresh(3XCURSES) or wrefresh(3XCURSES) for the window. The current background character (and attributes) is used to clear the screen. PARAMETERS
win Is a pointer to the window that is to be cleared. ERRORS
OK Successful completion. ERR An error occurred. ATTRIBUTES
