4.3 Character Sets

When you invoke DECTPU, you can use one of the following keywords with the /CHARACTER_SET qualifier to specify the character set that you want DECTPU to use:

DEC_MCS (for the DEC Multinational Character Set)

ISO_LATIN1 (for the ISO Latin1 Character Set)

GENERAL (for other general character sets)

TPU$CHARACTER_SET (see the DCL help topic for this logical name)

Each character set is an 8-bit character set with 256 characters. Each character in a set is assigned a decimal equivalent number ranging from 0 to 255. Each character set uses an extension of the American Standard Code for Information Interchange (ASCII) character set for the first 128 characters. Table 4–1 shows the categories into which you can group the ASCII characters.
