Inputs formatted data from internal storage.
Syntax
DECODE ( count , format , unit , io-specifier-list ) [ in-list ]
count
is an integer expression that specifies the number of characters (bytes) to
translate from character format to internal (binary) format. cnt must
precede format .
format
specifies the format specification for formatting the data. format can be one
of the following:
• The label of a FORMAT statement containing the format specification.
• An integer variable that has been assigned the label of a FORMAT
statement.
• An embedded format specification.
format must be the second of the parenthesized items, immediately
following count . Note that the keyword FMT= is not used.
unit
is the internal storage designator. It must be a scalar variable or array
name. Assumed-size and adjustable-size arrays are not permitted. Note that
char-var-name is not a unit number and that the keyword UNIT= is not
used.
unit must be the third of the parenthesized items, immediately following
format .
io-specifier-list
is a comma-separated list of I/O specifiers. Note that the unit and format
specifiers are required; the other I/O specifiers are optional. The following
I/O specifiers can appear in io-specifier-list :
