1These directory and file type defaults are added by the Motif Resource Manager if missing from the file specification.

2xxxxxx = suffix from mktemp(3). Note that this file is invisible.

3These X resource files are used only by dmtpu and dxtpu.

OpenVMS system managers should note that the OpenVMS systemwide logical name is defined as TPU$SECTION to point to EVE$SECTION.TPU$SECTION. You can modify this logical to use a different default editing interface.

2.1.2 Startup Files

Command files and section files can create or customize a DECTPU editor or application. Initialization files can customize EVE or other layered applications by using EVE or other application-specific commands, settings, and key bindings.

A command file is a file that contains DECTPU source code. A command file has the file type .TPU and is used with the DECTPU /COMMAND=filespec qualifier. DECTPU tries to read a command file unless you specify /NOCOMMAND. The default command file is the file called TPU$COMMAND.TPU in your current directory, if such a file exists. You can specify a different file by defining the logical name TPU$COMMAND.

A section file is the compiled form of DECTPU source code. It is a binary file that has the default file type .TPU$SECTION. It is used with the qualifier /SECTION=filespec. The default section file is TPU$SECTION.TPU$SECTION in the area SYS$SHARE. The systemwide logical name TPU$SECTION is defined as EVE$SECTION. This definition causes the EVE editor to be invoked by default when you use the DCL command EDIT/TPU. You must specify a different section file (for example, /SECTION= my_section_file) or /NOSECTION if you do not want to use the EVE interface.
