5.5 Executing DECTPU Programs

Buffer-change journaling works properly with Ctrl/C. Therefore, if you are not using keystroke journaling, exiting from the editor is not necessary.

For more information on the effects of pressing Ctrl/C, see Section 4.9.4.14 and Section 4.9.4.16.

5.6 Using DECTPU Startup Files

DECTPU startup files are files that DECTPU reads, compiles, and executes during its initialization sequence.

There are three types of DECTPU startup files:

•Section files

•Command files

•Initialization files

5.6.1Section Files

A section file is the compiled binary form of a file that contains DECTPU source code. To direct DECTPU to execute a section file, use the appropriate command syntax for your section.

To execute a section file, use the /SECTION qualifier with the EDIT/TPU command or let DECTPU execute the default section file.

The default section file is TPU$SECTION. When DECTPU tries to locate the section file, DECTPU supplies a default directory of SYS$SHARE and a default file type of .TPU$SECTION. OpenVMS systems define the system-wide logical name TPU$SECTION as EVE$SECTION, so the default section file is the file that implements the EVE editor. To override the OpenVMS default, redefine

TPU$SECTION.

For more information on the /SECTION qualifier, see Section 2.6.13.

5.6.2 Command Files

A command file contains a series of DECTPU procedures followed by a sequence of TPU statements. To direct DECTPU to compile and execute a command file, use the appropriate command syntax, as explained in this section.

To specify a DECTPU command file, use either the /COMMAND qualifier with the EDIT/TPU command or let DECTPU compile and execute the default command file.

The default command file is TPU$COMMAND. When DECTPU tries to locate the command file, it supplies a default file type of .TPU. To direct DECTPU to compile and execute a particular command file, define the logical name TPU$COMMAND to be the file you want DECTPU to use. For more information on the /COMMAND qualifier, see Section 2.6.2.
