LNMTOOL, DECWINDOWS, Motif-based Logical Name Browsing Tool LnmTool is a Motif based Logical Name browser. By default, LnmTool at startup, the Main Table is created by extracting all the index definitions from LNM$DCL_LOGICAL. Those defs are then copied into the Modify Table list. Each process has a default list of logical name tables available to its environment. That list is located in the LNM$SYSTEM_DIRECTORY, which was earlier retrieved from an index definition of LNM$DCL_LOGICAL.
