Abstract
Add attributes to a dataset
1 Instruments/Modes
Instrument Mode
All All
2 Use

(eg. attributename=` \att1" \att2" ..').
attributetype yes string real|integer|string|boolean
A list of the attribute types, one for each attribute name
(eg. attributetype=` \string" \real" \string" ..').
withattributecommenty no boolean n
A list of switches to determine whether a comment is added
y Be careful with this switch when used with a list of attributes. It is only optional for elements occuring
after the last attribute with a supplied comment
(eg. withattributecomment=`y n n y').
attributecomment no string
Comments to be added to attributes, one for each `y' in the withattributecomment list
(eg. attributecomment=` \comment1" \comment2" ').
realvalue no real
A list of values, one for each real attribute
integervalue no integer
A list of values, one for an integer attribute
stringvalue no string
A list of values, one for a string attribute
booleanvalue no boolean
A list of value, one for a boolean attribute

This section documents warnings and errors generated by this task (if any). Note that warnings and
errors can also be generated in the SAS infrastructure libraries, in which case they would not be docu-
mented here. Refer to the index of all errors and warnings available in the HTML version of the SAS
