File Copying Procedures; Read/Only Files; Copying Files Between Disc And Cassette - AMSTRAD cpc 6128 User Instruction

Read/Only files
It is possible, using CP/M, to set any file to be Read/Only, and/or set to a special
System status in the directory. Such attributes can only be set or reset in the CP/M
environment, but are honoured by AMSDOS. For further details, see part 2 of this
chapter (SET utility).
Copying files between disc and cassette
There is no support in
CPIM
Plus for accessing tape files and copying them to disc, nor
for making tape files from disc. !fit is required to copy files in this way, then CP/M 2.2
(on Side 4 of your system discs package) must be used. CP/M 2.2 contains the utilities
C LOA D and C S A V E for these purposes, and are used as shown in the tables ahead.
File copying procedures
The tables ahead cover copying files of all sorts between disc and tape (if connected).
It assumes that no additional disc drive is connected. It is not possible to copy
protected BASIC programs to and from tape at all, nor to copy a binary file (such as a
machine code video game) to or from tape unless the load addresses are known.
Further details of the programs PIP, C LOA D and C S A V E are given in part 2 ofthis
chapter.
See the next 2 pages for the copying tables ....
