Quick documentation for UNARC and UNCR Both UNARC and UNCR have built in help screens... just type UNARC or UNCR to get help on command syntax. UNARC will extract standard .ARC or .ARK files. The simplest method is to extract all the files at once. For example, if you have a file called PROGRAM.ARK on drive A: and you want to extract all the files to drive B:, just put a copy of UNARC.COM on drive A: with your .ARK file and type: UNARC PROGRAM B: UNARCA is an 8080 version of UNARC that works in the same fashion. UNCR will uncompress most .?Z? files (where the ? can be any character). If you want to uncrunch a file called PROGRAM.DZC to the same drive it is already on, you would type the command: UNCR PROGRAM UNCR will also unsqueeze most .?Q? files (where the ? can be any character). The command syntax is the same. NOTE: UNARC will both extract multiple files from a single .ARC or .ARK file and uncompress them, while UNCR will usually be used on files that have been first extracted from a .LBR file (with DE-LBR on this disk). The complete documentation and in most cases the Z80 source code is available in the FOG Library for these programs.  .
