Copying files from disc to disc
AMSDOS fues with hea.ders
It is possible to copy this type offile in the CP/M
environment using PIP (see part 2 of
this chapter). Any file created by AMSDOS which has a header record (see 'AMSDOS
headers', previously described) will be copyable as a whole - disc to disc - but in
general the contents of the file will not be understood by any
CP/M
programs.
ASCIIfues
Files created by AMSDOS without headers are generally in ASCII, and are both
copyable and understood by
CP/M
programs. In particular it should be possible to
exchange ASCII program files, ASCII data files and ASCII text files freely between
AMSDOS and
CP/M
programs.
