ZLUX is a Library Utility eXtention written to take advantage of ZCPR 3.x features. It installs itself as a Z3 shell, instead of moving itself under the CCP (and taking memory) like the original LUX program. Version 2.7 of ZLUX will now attach to .LZH and .ZIP files, as well as .LBR, .ARC, and .ARK files. Also optionally supports TCAP functions, such as clear screen and standout mode.
