1 /AFTER
/AFTER (D)
/AFTER[=directory-spec]
Specifies that LSE should insert the directory or directories
indicated into the list of source directories in back of the
directory you specify as the value on the qualifier. If you do
not specify a directory-spec value, LSE adds the directory or
directories to the end of the list.
If you do not specify either the /AFTER qualifier or the /BEFORE
qualifier, LSE replaces the entire directory list.
2 /BEFORE
/BEFORE
/BEFORE[=directory-spec]
Specifies that LSE should insert the directory or directories
indicated into the list of source directories in front of the
directory you specify as the value on the qualifier. If you do not
specify a directory-spec value, the directory or directories are
added at the front of the list.
If you do not specify either the /BEFORE qualifier or the /AFTER
qualifier, LSE replaces the entire directory list.
