1. The reason I wrote 'getimage(x-3,y-2,...)' is when I wrote 'getimage(x,
y,...)' it did'nt cover the complete text because the characters sometimes
goes over the actual starting point a little.
2. As for the char[70] parameter, I did that because in my program (which I
was using it for) I used char[70] right through it!
I did'nt need to put anything else in it! But I've changed it now!
3. (How do you check if LOOP (num) characters fits within your allocated
image buffer?) Good point! How do you?

when i try to run it from the .EXE file it seems to behave differently. The
problem is I've created a function similar to 'cin.getline()' but for 'BGI'
graphics, the function works fine when i run it in Dev-C++.

the .EXE file it has a problem with the delete feature in 'void
bgi_getline(int, int, char, int)' As you can see in the code it gets the
image of the background first with 'getimage()' then puts it back with
'putimage()' so you can see the new string. In the .EXE file it deletes but
you can still see the old string there! For some weird reason it is not
using the 'getimage()' and 'putimage()' functions properly!
