COBOL Manual for TNS/E Programs (H06.08+, J06.03+)

system-file-name-word
is a single user-defined word that specifies the name of an operating system file, not qualified
by any system name, volume name, or subvolume name. It cannot be a nonnumeric literal. It
cannot represent a DEFINE name.
file-mnemonic
is a name you choose as an alias for the operating system file name or (in the Guardian
environment) the DEFINE name. You can use it in ACCEPT, CALL, DISPLAY, and ENTER
statements.
ALPHABET Clause
The ALPHABET clause provides a way for you to associate a name with a specified character code
set, collating sequence, or both. You can use the alphabet-name that you define in the ALPHABET
clause in:
• PROGRAM COLLATING SEQUENCE clause of the OBJECT-COMPUTER paragraph
• COLLATING SEQUENCE phrase of a SORT or MERGE statement
• CODE-SET clause of a file description entry
alphabet-name
is a user-defined word, the name to be associated with the character code set that you define.
STANDARD-1, STANDARD-2, NATIVE
specify the USASCII character set.
EBCDIC
specifies the Extended Binary-Coded Decimal Interchange Code.
literal-phrase
defines an alphabet explicitly. An alphabet-name defined by literal-phrase cannot
be used in the CODE-SET clause in a file description entry. If you use literal-phrase, you
cannot specify a given character more than once in the ALPHABET clause.
