Error Messages; Amsdos External Commands; All External Commands - AMSTRAD cpc 6128 User Instruction

If the first character of the filename is ! then the above messages will be suppressed,
and you will not be required to 'press any key' for the file to be saved. (You must make
sure that the RECORD and PLAY buttons on your cassette unit are down.) If your
programs use the ! mark and are also required to run on disc, the ! mark will be
ignored during disc operation (when the disc file name is being read). Note that the!
mark does NOT occupy one of the character positions in the cassette or disc filename.
Abandoning the command using the [ESC] key produces the error message on the
screen:
