SWAPCOPY
--------
A file transfer utility for single drive systems.
Swapcopy has been designed to allow a single drive system
to be used to transfer any file or group of files from diskette
to diskette. There are no restrictions on the number or size of
the files.
The program reads the file specification given in the
command line, prompts the user to insert the disk containing the
source files, and begins reading files until the transient
program area is full or all the files have been read into memory.
The user is then prompted for the destination disk, and the files
are written out.
If the entire transfer can be completed in one pass, the
user is prompted to insert a system disk (i.e., one which has
CP/M on it) in drive A, at which point control is returned to
CP/M.
If more than one pass is necessary, the user will again
be asked for the source disk, then the destination disk, and so
on, until all the files have been transfered.
------------------
The command syntax
------------------
The command line expected is as follows:
A>swapcopy <file specification> [p][q][r]<cr>
where <file specification> is an ambiguous or unambiguous file
specification, and [p], [q], and [r] are options, as explained
below.
-------------------
Response to prompts
-------------------
When the system has asked for a particular disk, you
should hit return to acknowledge that the disk is ready. You may
instead hit control 'C' to abort the copy program. Any other
response will print a message which explains the acceptable
responses to the user.
-----------
The options
-----------
There are three options available: the 'Print' option,
the 'Query' option, and the 'Report' option.
The Print option will print an 'O' each time a source
file is opened, a 'C' each time a destination file is closed, an
'M' each time a new file is made, and an 'r' or 'w' for each
sector read or written. This option was put in mainly for
debugging and verification, but it makes an interesting display.
The Query option will print the name of each file which
matches the file name given in the command line, and ask the
operator if the file under consideration should be copied. Any
response beginning with 'Y' or 'y' is taken as affirmative, while
any other response will bypass the file.
The Report option prints the name of each file transfered
when the complete file has been copied to the destination disk.
