Thank you. I will do that. I didn't even know about this command to do a 'man' help with it.
This solved a big problem for me. We did a software upgrade on last Saturday (Aug 7th) and after the upgrade this started happening. Our operations staff were confused when the cursor was blinking in the middle of the screen waiting for input, and there still was displayed text on the bottom half of the screen. They had to type over what was on the screen. This can be confusing to anybody. For the time being, I put a screen clear command, but then they had to scroll back a few lines to see the last message. That wasn't very good either. I have done cursor positioning on VMS, (thru cobol too a few years ago), and I knew there had to be something on UNIX. I have always received solutions here when I have asked for it. This forum is very helpful for all users.
Thanks again.

show_mouse
show_mouse(3alleg4) Allegro manual show_mouse(3alleg4)
NAME
show_mouse - Tells Allegro to display a mouse pointer on the screen.
SYNOPSIS
#include <allegro.h>
void show_mouse(BITMAP *bmp);
DESCRIPTION
Tells Allegro to display a mouse pointer on the screen. This will only work if the timer module has been installed. The mouse pointer will
be drawn onto the specified bitmap, which should normally be `screen' (see later for information about bitmaps). To hide the mouse pointer,
call show_mouse(NULL).
Warning: if you draw anything onto the screen while the pointer is visible, a mouse movement interrupt could occur in the middle of your
drawing operation. If this happens the mouse buffering and graphics drawing code will get confused and will leave 'mouse droppings' all
over the screen. To prevent this, you must make sure you turn off the mouse pointer whenever you draw onto the screen. This is not needed
if you are using a hardware cursor.
Note: you must not be showing a mouse pointer on a bitmap at the time that the bitmap is destroyed with destroy_bitmap(), e.g. call
show_mouse(NULL); before destroying the bitmap. This does not apply to `screen' since you never destroy `screen' with destroy_bitmap().
