Thanks for the Responses
Thanks Gurus! I never heard of or used DOS2UNIX so maybe I will try it sometime. I did take a look at my FTP settings and it was set on "Automatic." After changing it to "ASCII," I FTPd some files over that I had problems with in the past. Sure enough, no more problems with character formatting! I guess I assumed that "Automatic" would always give me the best method of moving the file.
I still would also be interested in knowing why I am not able to use the command %s/^M//g. The commands I am using to get the formatting character are ctrl v followed immediately by ctrl m. There is no use of the shift key, minus signs, plus signs, etc - only the ctrl button with the letter v follwed by the ctrl button and the letter m.

readkey
readkey(3alleg4) Allegro manual readkey(3alleg4)
NAME
readkey - Returns the next character from the keyboard buffer. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int readkey();
DESCRIPTION
Returns the next character from the keyboard buffer, in ASCII format. If the buffer is empty, it waits until a key is pressed. You can see
if there are queued keypresses with keypressed().
The low byte of the return value contains the ASCII code of the key, and the high byte the scancode. The scancode remains the same whatever
the state of the shift, ctrl and alt keys, while the ASCII code is affected by shift and ctrl in the normal way (shift changes case,
ctrl+letter gives the position of that letter in the alphabet, eg. ctrl+A = 1, ctrl+B = 2, etc). Pressing alt+key returns only the scan-
code, with a zero ASCII code in the low byte. For example:
int val;
...
val = readkey();
if ((val & 0xff) == 'd') /* by ASCII code */
allegro_message("You pressed 'd'
");
if ((val >> 8) == KEY_SPACE) /* by scancode */
allegro_message("You pressed Space
");
if ((val & 0xff) == 3) /* ctrl+letter */
allegro_message("You pressed Control+C
");
if (val == (KEY_X << 8)) /* alt+letter */
allegro_message("You pressed Alt+X
");
This function cannot return character values greater than 255. If you need to read Unicode input, use ureadkey() instead.
