Syntax

ATTRC(data-set-id,attr-name)

Arguments

data-set-id
specifies the data set identifier that the OPEN function returns.

attr-name
is an attribute name. If attr-name is invalid, a missing value is returned.

Valid values for use with attr-name are:

CHARSET
returns a value for the character set of the machine that created the data set.
empty string Data set not sorted
ASCII ASCII character set
EBCDIC EBCDIC character set
ANSI OS/2 ANSI standard ASCII character set
OEM OS/2 OEM code format

ENCRYPT
returns 'YES' or 'NO' depending on whether the SAS data set is encrypted.

ENGINE
returns the name of the engine that is used to access the data set.

LABEL
returns the label assigned to the data set.

LIB
returns the libref of the SAS data library in which the data set resides.

MEM
returns the SAS data set name.

MODE
returns the mode in which the SAS data set was opened, such as:
I INPUT mode allows random access if the engine supports it; otherwise, it defaults to IN mode.
IN INPUT mode reads sequentially and allows revisiting observations.
IS INPUT mode reads sequentially but does not allow revisiting observations.
N NEW mode creates a new data set.
U UPDATE mode allows random access if the engine supports it; otherwise, it defaults to UN mode.
UN UPDATE mode reads sequentially and allows revisiting observations.
US UPDATE mode reads sequentially but does not allow revisiting observations.
V UTILITY mode allows modification of variable attributes and indexes associated with the data set.

MTYPE
returns the SAS data library member type.

SORTEDBY
returns an empty string if the data set is not sorted. Otherwise, it returns the names of the BY variables in the standard BY statement format.

SORTLVL
returns a value that indicates how a data set was sorted:
Empty string Data set is not sorted.
WEAK Sort order of the data set was established by the user (for example, through the SORTEDBY data set option). The system cannot validate its correctness, so the order of observations cannot be depended on.
STRONG Sort order of the data set was established by the software (for example, through PROC SORT or the OUT= option in the CONTENTS procedure).

SORTSEQ
returns an empty string if the data set is sorted on the native machine or if the sort collating sequence is the default for the operating environment. Otherwise, it returns the name of the alternate collating sequence used to sort the file.

TYPE
returns the SAS data set type.
