This command is similar to COPY except that it copies a file from a QL Format disk to an Atari Format disk. No conversion takes place.
You will need to pass the Atari filename in quote marks if it includes a three letter extension preceded by a dot eg:
ACOPY flp1_PROGRAM_BAS, “flp2_PROGRAM.BAS”
QCOPY copies a file from an Atari disk to a QL disk.
