Getting Started with DECTPU

2.6 Using OpenVMS EDIT/TPU Command Qualifiers

The choice of character set also affects how your text appears when printed. For the text displayed in DECTPU to look the same when printed, you must choose the same character set for both DECTPU and the printer.

There are two ways to specify the character set you want to use:

•Define the TPU$CHARACTER_SET logical name to specify the character set.

This lets you use that character set for all editing sessions—including when you invoke DECTPU within MAIL or other utilities. You can put the definition in your LOGIN.COM file. For example, the following commands define TPU$CHARACTER_SET as ISO_LATIN1 and then use that character set to invoke DECTPU:

$ DEFINE TPU$CHARACTER_SET ISO_LATIN1 $ EDIT/TPU

•Use /CHARACTER_SET= and specify the character set on the command line.

This overrides any definition of the TPU$CHARACTER_SET logical name. By default, DECTPU uses the DEC_MCS character set. For example, the following command specifies the GENERAL character set to invoke DECTPU. DECTPU uses the current character set to display 8-bit characters and does not use the default DEC Supplemental Graphics character set.

$ EDIT/TPU/CHARACTER_SET=general

If the character set you specify either with /CHARACTER_SET or by defining TPU$CHARACTER_SET is invalid, the editing session is aborted, returning you to the DCL level.

Table 2–3 shows the values you can specify with the /CHARACTER_SET qualifier or the TPU$CHARACTER_SET logical name.

Table 2–3 Character Set Values You Can Set with /CHARACTER_SET

Value

Description

 

 

DEC_MCS

This is the default setting that uses the DEC Supplemental

 

Graphics character set containing supplemental and

 

multinational characters, such as letters with accents and

 

umlauts.

ISO_LATIN1

This character set contains supplemental and multinational

 

characters that contain LATIN1 characters, such as the non-

 

breaking space, multiplication and division signs, and the

 

trademark sign.

GENERAL

DECTPU does not specify a character set for 8-bit characters.

 

8-bit characters are displayed the same as they were before

 

you started DECTPU.

 

 

2.6.2 /COMMAND

/COMMAND[[=filespec]]

/NOCOMMAND

/COMMAND=TPU$COMMAND.TPU (default)

The /COMMAND qualifier determines whether DECTPU compiles and executes a command file (a file of DECTPU procedures and statements) at startup time. Command files extend or modify a DECTPU-based application or create a new application. The default file type for DECTPU command files is .TPU. You cannot use wildcards in the file specification.
