GETLATTR

Category:

List

attributes

contains a string of words separated by blanks. Each word is a separate attribute for a list or item.

Type: Character

list-id

contains the identifier of the list that GETLATTR processes. An invalid list-id produces an error condition.

Type: Numeric or List

index

is the position of the item in the list. The position can be specified as a positive or negative number. By default, index is 1 (the first item). If index is a positive number, then the item is at position index from the beginning of the list. If index is a negative number, then the item is at position ABS(index) from the end of the list. An error condition results if the absolute value for index is zero or if it is greater than the number of items in the list.

If index is 0 or is omitted, then the attributes returned by GETLATTR are list attributes. If index is nonzero, then GETLATTR returns the attributes associated with the indexed item instead of the attributes for the entire list.

Type: Numeric

Details

The items in attributes can be used to assign attributes to another list or item. The string returned as attributes contains a blank before and after each attribute, which makes it easy to determine whether an attribute is set by searching attributes for an attribute name. Use the INDEX function to search the string for a specified attribute.

If index is omitted, attributes contains one attribute from each row of the following table:

Default Setting		Alternate Setting
UPDATE		NOUPDATE
NOFIXEDTYPE		FIXEDTYPE
NOFIXEDLENGTH		FIXEDLENGTH
ANYNAMES		SASNAMES
DUPNAMES		NODUPNAMES
NOCHARONLY		CHARONLY
NONUMONLY		NUMONLY
COPY		NOCOPY
HONORCASE		NOHONORCASE

If index is supplied, then attributes is the set of item attributes consisting of one attribute from each row of the following table:

Default Setting		Alternate Setting
ACTIVE		INACTIVE
DELETE		NODELETE
NOFIXEDTYPE		FIXEDTYPE
UPDATE		NOUPDATE
WRITE		NOWRITE

For detailed information about these attributes, see SETLATTR.

Example

Create a list LISTID with one item and print the sets of list attributes for LISTID as well as the item attributes that are associated with the first item of LISTID. Note the leading and trailing blanks in the attribute strings, which are made evident by embedding the attribute strings in double quotation marks.

INIT:
   listid = makelist(1);
   listattrs = '"' || getlattr(listid) || '"';
   put listattrs=;
   found = index(listattrs,'UPDATE');
   put found=;
   itemattrs = '"' || getlattr(listid,1) || '"';
   put itemattrs=;
   rc = dellist(listid);
return;

LISTATTRS=" DELETE UPDATE NOFIXEDTYPE
NOFIXEDLENGTH ANYNAMES DUPNAMES
NOCHARONLY NONUMONLY COPY NOHONORCASE"
FOUND=10;
ITEMATTRS=" ACTIVE WRITE NOAUTO NOEDIT
DELETE UPDATE NOFIXEDTYPE "

FOUND returns the starting position of the word "UPDATE" in the string of list attributes.
