- DESCRIPTION:
- ============
-
- CSWEEP is a file copy program similar in function to the popular SWEEP and
- NEWSWEEP programs. Unlike these programs, CSWEEP operates entirely from
- command line options and has no interactive mode. In this respect it is
- similar to Digital Research's PIP program. CSWEEP however, offers the
- following options not available with PIP.
-
- ** Multiple copies on different drive/user areas with a single operation.
-
- ** ZCPR3 style drive/user access. Source and destination files may be on
- any drive (A thru P) or user area (0 thru 31).
-
- ** Source file may be deleted after copying (-d option)
-
- ** True CRC file copy checking (-v option)
-
- CSWEEP is extremely useful for copying or moving files with any program or
- operating system that uses command files, such as SUBMIT. It will also
- save many keystrokes over SWEEP or NEWSWEEP when moving large numbers of
- files around in your disk system.
-
-
- USAGE:
- ======
-
- The command line format for CSWEEP is:
-
- CSWEEP f1 [f2 .. fn] sdu: ddu1: [ddu2: ... ddu6:] [-v] [-d]
-
- Optional command arguments are in square brackets. The arguments are:
-
- f1 .. fn -- file names to copy (may be ambiguous)
- sdu: -- source disk/user (e.g. a0:)
- ddu1: .. ddu6: -- destination disk/user
- -v -- verify copies (CRC)
- -d -- delete source copies
-
- All drive/user designations are in the form of a drive letter followed by
- an OPTIONAL user area number followed by a colon, as in the example above.
- Any other format will be flagged as an error. The current user area is
- assumed if none is given.
-
- Filenames, drive/user specs and options may be given in any order with the
- exception that the first valid drive/user spec encountered will be
- interpreted by CSWEEP as the source d/u for copying.
-
-
- AMBIGUOUS FILE NAMES:
- =====================
-
- CSWEEP accepts ambiguous file names of the standard CP/M sort with one
- addition. An ambiguous file name (afn) preceded by a "!" causes all names
- matching the given afn to be EXCLUDED from the resulting copy. Thus, to
- copy all files except "COM" files from a: to b:, say:
-
- CSWEEP *.* !*.com a: b:
-
- When giving a "!" afn, "*" chars in the string match to the end of either
- the filename or extension, just like CP/M, but "?" chars match ONE and
- ONLY ONE character in either the filename or extension.
-
-
- OPTIONS:
- ========
-
- CSWEEP accepts two command options which must be preceded by a "-" sign.
-
- -D Delete the source file after all copies have been made. If a write
- error of any sort occurs during a file copy, the source file will NOT
- be deleted.
-
- -V Verify each copy with a CRC (Cyclic Redundancy) check. This option
- will slow down the operation of CSWEEP considerably since each copy
- file must be read back and verified against the CRC of the source.
-
-
- OPERATION:
- ==========
-
- CSWEEP will copy all files as instructed unless a BDOS file error is
- encountered in the copy process. If an error occurs in creating or
- writing to a copy file, CSWEEP will report the error, delete the partial
- copy (if any) and drop the disk/user in which the error occurred from
- further copy operations. After completing it's work, CSWEEP will report a
- tally of files copied and errors encountered.
-
- If your CP/M system memory is exceptionally small (less than 48K) you may
- receive an "Out of Memory" error when you attempt to run CSWEEP. If your
- operating system is of the type which takes proprietary control of
- portions of high memory (such as ZCPR3) CSWEEP may crash or simply lock
- up. If this happens, you may use any convenient debugger or disk utility
- to change the byte at address 16B8 hex (157D hex if referenced to 0 rather
- than 100 hex). This byte follows the word "MEMORY" in memory and
- determines the number of 128 byte sectors read into memory at one time. A
- small value here will assure the safety of your operating system, but will
- cause the program to run quite slowly. The default in the program as
- distributed is 180 sectors, or about 22K. Thus CSWEEP requires a total of
- c.a. 38K bytes to operate. This should not present a problem to most
- operating systems.

- routines which make up the main body of the code for CSWEEP, and also for
- the documentation for the wildexp function which is paraphrased in the
