FILE-CONTROL Paragraph
file-name
is the COBOL file-name (the file-name in a file description entry).
ASSIGN clause
associates file-name with a file designated by system-file-name, or
define-name-literal. Only the first system-file-name or define-name-
literal has meaning. The compiler ignores subsequent names and literals and
issues a warning.
system-file-name
is the name of a disk file or either of the special operating system file names
#DYNAMIC or #TEMP, described in System-Names. system-file-name
must be enclosed in quotation marks unless it begins with a dollar sign ($), a
backward slash (\), or a number sign (#), or is a COBOL word. If system-
file-name is #TEMP, the file cannot have alternate keys. For more
information about operating system file names, see the Guardian Procedure
Calls Reference Manual.
define-name-literal
is a nonnumeric literal that represents the name of a DEFINE of class MAP
that is associated with a disk file. Quotation marks must enclose any DEFINE
name. For information about DEFINE names, see DEFINEs.
RESERVE clause
enables or prevents sequential block buffering on input and buffered cache on
output, or enables or prevents HP COBOL Fast I-O for both input and output, for a
disk file, depending on the value of number.
