By default, if you specify
the AUTOEXEC, CMPLIB, FMTSEARCH, HELPLOC, MAPS, MSG, SASSCRIPT, SASAUTOS,
SASHELP, or SET system option more than one time, the last specification
is the one that SAS uses. If you want to insert additional pathnames
in front of the search paths that have already been specified by one
of these options, you must use the INSERT or APPEND system options
to append the new pathname. For example, if you entered the following
SAS command, the only location that SAS will look for help files is
c:\app2\help, and the output of PROC OPTIONS will
only show
c:\app2\help:
sas -helploc “c:\app2\help”
If you want
SAS to look in both the current path for help files and in
c:\app2\help and if you want SAS to search
c:\app2\help first, then you can append the new
location to the value of the HELPLOC option using the INSERT option:
sas -insert helploc “c:\app2\help”
If
your current path for help files is
!sasroot\nls\en\help, then for the value of the HELPLOC option, PROC OPTIONS will now
show
(“c:\app2\help” “!sasroot\nls\en\help”)
