Getting Started with DECTPU
2.1 Invoking DECTPU on OpenVMS Systems
2.1.1 Default File Specifications
Table 2–1 lists the default TPU and EVE file specifications on OpenVMS systems.

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

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