Getting Started with DECTPU 2.6 Using OpenVMS EDIT/TPU Command Qualifiers

$ EDIT/TPU/RECOVER/JOURNAL=save.TJL letter.dat

In EVE, you can use /RECOVER to recover either an editing session from a keystroke journal file or a single buffer from a buffer-change journal file. If you specify /JOURNAL=filename, EVE recovers from the specified keystroke journal file. Otherwise, EVE recovers from a buffer-change journal file that corresponds to the input parameter (or the buffer specified on the command line if no input parameter is specified).

For more information on journaling and recovery in EVE, see the Extensible Versatile Editor Reference Manual.

2.6.13 /SECTION

/SECTION[[=filespec]]

/NOSECTION

/SECTION=TPU$SECTION (default)

The /SECTION qualifier determines whether DECTPU loads a section file. A section file is a startup file that contains key definitions and compiled procedures in binary form.

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$SECTION. OpenVMS systems define the systemwide logical name TPU$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.

You can specify a different section file. The preferred method is to define the logical name TPU$SECTION to point to a section file other than the default file. You can also supply a full file specification for the /SECTION qualifier.

For example, if your device is called DISK$USER and your directory is called [SMITH], the following command causes DECTPU to read a section file called VT100INI.TPU$SECTION:

$ EDIT/TPU/SECTION=disk$user:[smith]vt100ini

If you omit the device and directory in the file specification, DECTPU assumes the file is in SYS$SHARE. The section file must be located on the same node on which you are running DECTPU.

To determine whether /SECTION was specified on the DCL command line, use the following call in the application:

x := GET_INFO (COMMAND_LINE, "section");

The preceding call returns 1 if /SECTION was specified, 0 otherwise. To fetch the name of the section file specified on the command line, use the following call:

x := GET_INFO (COMMAND_LINE, "section_file");

For more information on GET_INFO, see the DEC Text Processing Utility Reference Manual.

You must compile the file used as the value for the /SECTION qualifier. To do so, run the source code version of the file through DECTPU and then use the built-in procedure SAVE. This process converts the file to the proper binary form.

For more information on creating and using section files, see Chapter 5.
