It is a shell program for people who don't like dealing with command line options. SHEZ lets you view and use archived files from a number of programs, PKZIP, ARC, PKARC, PAK, and LZH. You need the archive programs themselves in order for this to work. You have to run the SHEZCFG program to configure SHEZ to work. It is all explained in the documentation. It is also a DOS shell, sort-of. > Okay, a third bonus question: > 3) My system (see above) has 1 meg RAM. I do not have Windows 386.

The rest is for your video adapter and ROM BIOS. There's nothing unless you want to buy an extended memory manager, but that's a whole new long subject altogether. -- Eugene Wang eggbert@bucsf.bu.edu
