The FMTSEARCH= system option adds the PROCLIB.FORMATS catalog to the search path that the SAS System uses to find user-defined formats. The FMTSEARCH= system option requires only a libref. FMTSEARCH= assumes the catalog name FORMATS if no catalog name appears. Without the FMTSEARCH= option, SAS would not find the NOZEROS. format.(footnote 1)
