System-wide@ installation will require a DEFINE /SYSTEM . Not Mandatory !!! 2) Executable& You can chose one of the following :L o Copy the executable where you want it to be and define a foreign symbol  DX :== $disk:[dir]DXI o Insert DX.CLD in DCLTABLES, change DX$HOME to where the executable is= installed (if not in DX$HOME), copy the EXEcutable there.5 o Place DX.EXE in DCL$PATH (OpenVMS 6.2 or upper).   3) Help Library!

Ex :. define/system DX$HELPLIB APPSDOC:DXHELP.HLBO Note : In principle, you do not need to define DX$HELP. I personally place theO .HLB file in DX$HELP and insert DX.CLD DX$HOME into VMSAPPS: a directory where% all of our VMS freeware are located.AUTHOR9 Original Author : Chau-Kuang Hung (chung@us.oracle.com)@ Maintained by : Jérôme Lauret (jlauret@mail.chem.sunysb.edu) 3 Please send comments bug report and suggestions to jlauret@mail.chem.sunysb.edu.
