* ArcPop is a compact, easy to use file de-archiver with the
special feature of making self-extracting archives. Operates
on ArcMac archives and on the standard MS-DOS archives
(compatible with SEA's ARC version 5.12)
* Works on current model Macintoshes with 128K or larger ROMS
(Mac+, MacSE, MacII).
* Requires approximately 100 kilobytes of free memory.
ArcPop Usage
------------
ArcPop is a small and simple de-archiving application. In the
ArcMac.Arc distribution archive, ArcPop is the application which
extracts the archived material. You can separate ArcPop from the
ArcMac.Arc archive by choosing the "Unmake ArcPop" button when
you launch ArcMac.Arc. Version 1.1 adds support for "squashed"
packing of PKArc and ArcMac.
ArcPop's choices are limited to
(1) extract all the files in an archive
(2) make an archive into a ArcPop self-extracting archive
(3) unmake a ArcPop-archive combination.
You can launch ArcPop alone, then select an archive name on the
dialog. Version 1.1 adds a standard file get button, the <<Get
Archive:>> button. Use this to let your mouse do the walking
through folders to select an archive to unpack. All files in the
archive are unpacked to the current folder; the file name
and an indicator bar show the progress of unpacking.
You can also shift-select ArcPop and a regular ArcMac archive, or
an IBM style archive, from Finder and then launch ArcPop. In
this case the selected archive will be your default to operate
on. If ArcPop already contains an archive in its data fork, the
name of the ArcPop file will be the default archive to operate
on.
Creating a ArcPop from a regular ArcMac archive is simple.
Launch ArcPop and select the name of the archive to make self-
extracting. Click the Make ArcPop radio button. Click continue.
ArcPop copies itself to the resource fork of the archive, making
it an application. ArcPop adds about 20 kilobytes to the size of
an archive. This makes it unwise to turn all archives that are
to be placed on bulletin boards into ArcPops. However, when you
want to send archives to others that are unlikely to have an
archive extractor, or want to pack a lot of data onto a disk and
retain extracting ability on the disk, ArcPop is a useful tool.
Two modifiers for ArcPop are the G, unGarble option for encrypted

archives, and the I, strip IBM controls option.
If the archive has been encrypted, you will need to enter the
proper password (either upper or lower case will do), and click
the Password check box.
If the archive is from an MS-DOS or IBM machine, and contains
text files, then you will want to click the eat linefeeds check
box. All control characters other than carriage returns will be
removed from the extracted files. If an IBM archive contains a
mixture of text and other data files, you will need to use ArcMac
to selectively extract files with control stripping.
There is a minor glitch in Finder running under MultiFinder
(Apple System 5.0 release) that causes updates of a file's finder
information not to be reflected in an open Finder window. When
you make an ArcMac archive into an ArcPop self-extracting
archive, the file's icon and its finder info does not get updated
in Finder's open window, even though it is updated on the disk.
What you need to do is simply to close the Finder window with the
new ArcPop archive, then re-open it. Lo and behold, it's icon
has now changed to the "A" button.

ArcMac Distribution Files
-------------------------
ArcPop.ARC -- This is the ArcPop de-archive utility only,
with self-extracting documention. ArcPop is
distributed freely, so than no one need pay to
access available ArcMac'ed data. If you don't care
for ArcMac, but want the capability of using
ArcMac'ed (or IBM/MS-DOS arc'ed) files, this is
the tool for you.
ArcMac.ARC -- includes the full ArcMac file archiver / de-
archiver, ArcPop, ArcMac.Doc, and xArcMac.
MARCS.ARC -- this archive contains Turbo Pascal source for
the xArcMac and the ArcPop programs, so that
others may incorporate the ArcMac file structure
and protocol in archivers.
Current versions of these files can be obtained from
Bloomington's PC-LINK bulletin board, phone 812-335-7272
(1200..9600 Baud, 24hr).
The CompuServe MACPRO Maug Sig and BORPRO Borland Sig will
generally have the most recent updates.
