- ARCE Command Version 2.11
- ------------ Jan 24, 1987
-
-
- Purpose:
- To extract files from an ARC archive file.
-
- Format:
-
- ARCE [d:][path]filename.ext [filespecs...] [d:outpath]
- [/R] [/Q] [/P]
-
- Remarks:
-
- The drive and path names are optional. If omitted, the current
- drive and path name is used.
-
- The filename must be supplied. The extension defaults to ARC.
- All files matching the supplied filename are processed. The ARC
- filename may contain the * and ? wildcard characters.
-
- If no filespecs are supplied, all files are extracted.
- Otherwise, only those ARC members which match one of the up to
- 16 filespecs are extracted.
-
- The extracted files may be placed on another drive, and/or in
- another subdirectory by following the optional filespecs with a
- drive designator and/or path name.
-
- If the file being extracted already exists, you are asked
- whether or not you want to over-write it. You may use the | /R
- option to bypass this prompt. Use a Y followed by the | return
- key to over-write the file.
-
- Use the /Q option to suppress alarm sounds, beeps, and bells.
-
- Use the /P option to write the extracted files to the DOS
- standard output file. With /P, you may pipe or redirect the
- output. An initial line feed is added to the beginning of the
- output file.

-
-
- Examples:
- --------
-
- o Extract all file from TEST.ARC onto the current drive:
-
- ARCE TEST
-
- o Extract only file with an extension of .ASM from the archive
- SOURCE.ARC on drive B and in subdirectory SAVE:
-
- ARCE B:\SAVE\SOURCE *.ASM
-
- o Extract all files from all ARC files in the subdirectory
- called TEST on drive C:
-
- ARCE C:\TEST\*
-
- o Extract all files from PROGA.ARC and place the files in
- subdirectory OLD on drive B:
-
- ARCE PROGA.ARC B:\OLD
-
- o Extract all files with an extension of .COM and .EXE from the
- archive PROGS.ARC in directory NEW\WORK on drive B, and place
- the them in subdirectory SAVE\TEST on drive A; replace
- existing file:
-
- ARCE B:\NEW\WORK\PROGS *.COM *.EXE A:\SAVE\TEST /R
-
- o Extract the file READ.ME from the archive GIZMO.ARC and
- display it on the console instead of writing it to a file:
-
- ARCE GIZMO READ.ME /P
-
- o Same as above, except pass the extracted READ.ME file to the
- LIST file viewer:
-
- ARCE GIZMO READ.ME /P | LIST /S

- Error Messages:
- --------------
-
- 'filename - premature EOF reading '
-
- Data is missing from the archive file. The program is
- terminated.
-
-
- 'filename - unable to set file datestamp'
-
- The file datestamp is set to the current date and time, and the
- next archive member is processed.
-
-
- 'filename - WARNING: file CRC does not match!'
-
- The extracted member is left on the output disk, and the next
- archive member is processed. The file is probably invalid but
- is left on the disk for your examination.
-
-
- 'Invalid filespec(s)'
-
- The filespec syntax is incorrect. The filename part may be from
- 1 to eight characters, and may include the ? or * wildcard
- characters. The extension may be none to three characters, and
- may include wildcards. There is a maximum of 16 filespecs
- allowed. The program terminates.
-
-
- 'filename - file already exists. Overwrite it? (y/N) '
-
- The member being extracted already exists. If you are using a
- data path utility, the file may not actually be in the
- subdirectory be used for output. Respond with the letter Y to
- over-write the existing file, or respond with the letter N to
- skip this member and continue to the next.
-
-
- 'Abort: Stack overflow'
-
- The member being extracted has invalid data. The program is
- terminated.
-
-
- 'filename - invalid decode tree count'
-
- The member being extracted has invalid data. The program is
- terminated.
-
-
- 'filename - new archive format 7 not yet supported'
-
- Format 7 is a special file compression method used internally by
- SEA, the authors of ARC. Processing continues with the next
- archive member.
-
-
- 'Unable to open archive > arcname'
-
- The specified ARC archive file was not found, or was
- inaccessible. The program terminates.
-
-
- 'CREATE failed > filename'
-
- There was insufficient directory space, or a failure accessing
- the output disk. The program terminates.
-
-
- 'Invalid archive format!'
-
- The archive file data is invalid. The program terminates.
-
-
- 'Incorrect DOS version'
-
- Version 2.0 or later of PC DOS must be used. The program
- terminates
-
-
- 'Not enough memory.'
-
- A minimum of 112k bytes of memory is required. The program
- terminates.
-
-
- 'I/O error reading from arcname'
-
- An incorrectable error occurred attempting to read data from the
- archive file. The program terminates.
-
-
- 'I/O error writing or disk full > filename'
-
- There was not enough disk space to write the complete archive
- member. The partially extracted file is scratched and the
- program terminates.
-
-
- 'No matching file(s) found'
-
- No archive files were found that matched the supplied filename
- specifications. The program terminates.
-
- || 'WARNING: Skippig Squashed File!'
-
- | A variant compression method has been used and the file can not
- | be properly extracted.
