Unless you are a previous (and recent) user of UCL+, your first step should be to print the documentation. It is con- tained in the file UCL.DOC and runs about 50 pages. The major components of this kit are: o UCL.SAV - the UCL+ program o UCLXM.SAV - a special XM version of UCL+ (RT-11 V05.02 or later only) o UCLHLP.TXT - the help text necessary to build a UCL+ help program o UC.SYS, UCX.SYS, UC.TSX - various flavors of the "UCL memory" handler o CI.SYS - the Command Line Interpreter handler (also RT-11 V05.02 or later only) Installation instructions for the various UCL+ components are included in the documentation. UCL+ supports RT-11 monitors starting with V5.0 and TSX-Plus starting with V4.1. It also runs under the RT-11 emulator (RTEM) on RSX-11 and VMS systems. It will support, without modification, the following command interpretation facilities: o UCL (User Command Linkage) for RT-11 and TSX-Plus o UCF (User Commands First) for RT-11 o UCI (User Command Interpreter) for TSX-Plus
