Now available via standard anonymous FTP from SIMTEL20... Filename Type Bytes CRC Directory PD1:<CPM.ARC-LBR> CPMARC.ARK BINARY 90391 1333H This ARK contains an ARC maker for CP/M (8080 or Z80) computers. There are two versions - one supports automatic compression with Huffman squeezing, packing or storing, along with DIR and delete member file - and another version with LZW crunching, packing or storing but without DIR or delete member file (it would be too big). The LZW version requires a large ( >60K ) CP/M and is much slower than the SQ version. Full C-language source, documentation and executables are included. This file is also available on my RCP/M and on GEnie's CP/M RoundTable. --Keith Petersen Arpa: W8SDZ@SIMTEL20.ARPA Uucp: {bellcore,decwrl,harvard,lll-crg,ucbvax,uw-beaver}!simtel20.arpa!w8sdz GEnie: W8SDZ RCP/M Royal Oak: 313-759-6569 - 300, 1200, 2400 (V.22bis) or 9600 (USR HST)

Be careful with the new ARC maker for CP/M. There are some problems that will have to ironed out in the next revision. The following message is from RCP/M Royal Oak (313) 759-6569. --cut-here--CPMARC.BUG--cut-here-- Date: 9-Nov-87 From: Lee Rimar To: All Re: CP/M ARK program I feel like a kid who got exactly the toy he wanted for Christmas -- but then found out it didn't work. After waiting over a year for a CP/M archive program, it's finally here. But it's slow and has some dangerous bugs. There are two versions: ARCS does file compression by Squeezing, ARCC does it by crunching. Each has it's own problems. ARCS bombs out if you try to put more than 64 files into an archive. It WILL close the archive correctly, but if you specified a file list or wild cards totally more than 64 files, it just aborts after the the 64th is arc'd. And it IS slow: I was trying to archive the initial program load for my RAMdisk, about 700K in 65 files. Took OVER AN HOUR to get the 64th file (RAMdisk to floppy). Then ten very noisy minutes of disk error retry, trying to figure out where to put the 65th file. Finally it aborted. ARCC has a different problem. The docs say it needs a TPA of AT LEAST 60K. I have 56K, and it works if you try to archive small files, and specify a small file list. BUT if you run out of memory, it DOES NOT exit gracefully -- it goes off into never-never land, and sometimes will trash your disk directory en route. ARCC is even slower than ARCS -- a single 12K file took about 5 minutes to archive (RAMdisk to RAMdisk) on my 4Mhz Kaypro. So even if you have the memory to run it, you might not have the time. If you need 'em, they're here -- but be careful . . .

Amen. Probably best said is to stay away from these utilities, ARCS and ARCC.
