| Where do we 'floppy disk based users' obtain a copy of this most
useful utility ????

| There's a POWERPACKER22A.ZOO on WJG::AMIGA:. This looks like 2.2a whereas
the base note says 2.3a...

| 2.3a is the latest.

2966.4 | PowerPacker questions... | SMAUG::SPODARYK | Binary Throttle | Fri Jan 05 1990 19:46 | 10 |
| Where would V2.3a be located?
Is this primarily useful for 'crunching' executables? Can I
'crunch' my IFF pictures, and then have PowerPacker 'expand'
them automagically for viewing with something like Superview?
What kind of performance hit does the 'de-crunching' phase
take when you want to run an application?

| It can crunch executables and text files, but you have to use the
'more' program included to view those files.
It won't do iff pictures, but I have seen one that does something
like that. If I run across it soon, i'll upload it.
It does seem make some programs load faster, but the de-crunch part
sometimes offsets that speed.
I have noticed that many crunched programs eat memory but does not
give it back. Dunno the reason why.

You need ppmore to view the "crunched" text file. Of course, you can
decrunch it and use any standard text file viewer.

IFF files don't seem to compress. For some reason, they tend to expand
when these compression programs are used.

Hmmm .. I doubt that they load faster. The file is actually decrunched
into memory and then run, so naturally it takes a few moments longer.
But, you'd need a pretty accurate stopwatch to notice the difference on
smaller programs.

I haven't noticed that. Have you tried "cleanram" or "flush" to free up
memory? Have you tried running the same programmed decrunched to compare
memory loss?

| I grabbed PowerPacker 2.3b off of one of the Fish Disks (#253, maybe)
and have played with it a bit. It does seem like a real nice
utility, and I have crunched some of my larger applications
down to ~1/2 their original sizes.
However, it doesn't seem to crunch anything compiled with Lattice C.
It comes back with an 'unknown hunk' type error. I know the
program will remove symbol/debug information to save space.
How is the compression related to the types of hunks it finds
in the executable? What compression/compaction algorithms might
it use?
~Steve ( no problems with PowerPacker 2.3b and memory usage )
