This small program was meant to change the cursor as well as display its position and button status. The cursor changes, but no text is appearing anywhere- just a blank screen. Plese help

Tried it, it works just fine for me. There's a bunch of stuff wrong with your code though.
First, what version of allegro are you using. You shouldn't be using textprintf anymore. Also, END_OF_MAIN(); is wrong. Drop the ; it's just END_OF_MAIN(). Next you should check the bitmap you're using, and AFAIK 24 is not a good color depth to use, but I might be wrong. Also, you're not destroying the bitmap once you're done. You needn't include string.h either.
set_gfx_mode(GFX_AUTODETECT_WINDOWED, 648, 480, 0, 0);
Odd resolution. Try 640x480, may be a little safer (definetly for full screen though.)
You shouldn't be using textprintf anymore.
Why not? What should be used instead?

Use makecol() to acquire a proper text color.
Why not? What should be used instead?
void textprintf_ex(BITMAP *bmp, const FONT *f, int x, int y, int color, int bg, const char *fmt, ...);
]]>Seems I misread your question a bit. I thought the mouse wasn't showing up either. Well, the answer is what gnolam said, the text is drawn, but for me it was a dark blue font, so you're not seeing it because of the black background. Trytextprintf_ex(screen, font, 10, 10, makecol(255, 255, 255), -1, "Mouse :(%d,%d,%d)",mouse_x,mouse_y,mouse_z);
edit:
A bit off topic, but textprintf is a link to the manual in the code box, but textprintf_ex isn't. Fix it ML
