ARCE CommandVersion 4.0e
------------Mar 17, 1989


Purpose: Use ARCE to extract files from an ARC archive file.

Format: The program name may be either ARCE or ARC-E.

ARCE [d:][path]filename.ext [filespecs...] [d:outpath]
[/R]
[/Q]
[/P]
[/T]
| [/5]
[/Gpassword]

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 nofilespecs are supplied, all filesare 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.

Use the /T option to test the archive's integrity. No files will
be extracted.

If the file was encrypted, use the /G option to supply the same
password as was used to create the file, e.g. /GSECRET.

|Use the /5 option to stop ARCE from creating the subdirectories
|for files created with the ARC /Z subdirectory option.

ARCE TEST

SOURCE.ARC on drive B and in subdirectory SAVE:

ARCE B:\SAVE\SOURCE *.ASM

o Extract all filesfrom all ARC files in the subdirectory
called TEST on drive C:

ARCE C:\TEST\*

o Extract all filesfrom 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
thethem in subdirectorySAVE\TEST on drive A; replace
existing file:

ARCE B:\NEW\WORK\PROGS *.COM *.EXE A:\SAVE\TEST /R

o Extract the file READ.MEfrom the archive GIZMO.ARC and
display it on the console instead of writing it to a file:

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

'Invalid filespec(s)'

The filespec syntax is incorrect. The filename part may be from
1 to eight characters, andmay 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.
