- ARCA - Add to Archive File
-
- Experimental Version 1.09
- (c) Wayne Chin and Vernon Buerg, 1986
-
-
- Purpose: To create or add files to an ARC archive file.
-
- Format: ARCA [d:][path]arcname.ext [filespecs...] [/D]
-
- Remarks: The drive and path names are optional. If omitted, the
- current drive and path name are used.
-
- The 'arcname' file name must be supplied. The extension
- defaults to ARC. All files matching the supplied filespecs are
- processed. The input 'filespecs' may contain the * and ?
- wildcard characters.
-
- If an existing archive file is used, the specified input
- files are added to the end of it. There is no checking
- for duplicate filenames. Existing archive member files
- are not replaced.
-
- Because only the crunching (LZW) method of compression is used,
- the archive file may not be identical to the archive file
- created by the ARC program from SEA, the authors of ARC.
-
- If the filename of the target archive file matches an
- input file specification, it is ignored.
-
- The /D option specifies that all input files be deleted. The
- files are deleted after successful processing of all of the
- input files.
-
-
- Examples:
- --------
-
- o Create an archive file called TEST.ARC, and place all
- files from the current directory into it:
-
- ARCA TEST *.*
-
- o Create an archive called SOURCE.ARC in the subdirectory
- \SAVE on drive B, and place all files with an extension
- of ASM into to:
-
- ARCA B:\SAVE\SOURCE *.ASM
-
-
- o Add files to the archive on drive A called PROGA.ARC all
- files in subdirectory \TEST on drive C, all files with a
- filename beginning with NE, and all file from the subdirectory
- \OLD on drive B:
-
- ARCA A:PROGA.ARC C:\TEST\*.* NE*.* B:\OLD\*.*
-
-
- Error Messages:
- --------------
-
- ARCA: filename, compressing, done.
- This message is issued for each 'filename' added to
- the archive file. The program continues.
-
-
- ARCA: No matching files!
- No files were found that matched one of the 'filespecs'
- in the command line. The program terminates.
-
-
- ARCA: You must use DOS version 2.0 or higher.
- DOS version 2.0 or higher is required. The program terminates.
-
- ARCA: Insufficient memory.
- A minimum of 34k is required. The program terminates.
-
-
- ARCA: Shrink failed.
- This error should not occur. If it does, there is a problem
- with DOS. The program terminates.
-
-
- ARCA: Can't create archive file.
- There is no room in the target directory to create the
- specified archive file, or the target disk has become full.

-
- This program uses new algorithms for compressing data.
- The resultant archive files will not match those produced
- by the SEA ARC program, but the files can be extracted by
- all ARC compatible programs.
-
- A major improvement in performance is due to the use
- of only one method for compressing and storing data.
- Future version may include other storage methods.
