Syntax

HELPLOC=itemstore | libref.itemstore | libref.itemstore-1, ...itemstore-n

itemstore
specifies the itemstore name, which is assumed to be in the library specified by the SASHELP= system option (SASHELP * by default) when no other libref is specified.

libref.itemstore
specifies an itemstore or series of itemstores in a library other than specified in the SASHELP= system option.

libref.itemstore-1, ...itemstore-n
specifies a series of itemstores that will be parsed in the order listed for the occurrence of a named item.

Details

The HELPLOC= system option identifies itemstores containing user-defined help. SAS resolves help links by searching through an ordered list of itemstores that begins with the latest specification of HELPLOC= and always ends with the default value HELPDOC. The default value is the name of the itemstore in the SASHELP library that contains all SAS Help information.

When a new itemstore is identified by specifying a new value for the HELPLOC= system option, SAS adds that new specification to the head of a list of specifications made previously in the current SAS session. The default value of HELPDOC is always retained at the end of the list of specifications, thereby ensuring the availability of SAS Help.

The following example shows how SAS constructs the ordered list of itemstores in response to multiple specifications of the HELPLOC= system option: 

proc options option=helploc;
options helploc=userhlp1;
proc options option=helploc;
options helploc=userhlp2;
proc options option=helploc;
run;
The LOG window shows that the value of the HELPLOC= system option changes from HELPDOC to USERHLP1, HELPDOC and then to USERHLP2, USERHLP1, HELPDOC.
