PFACTOR is called by FACTOR to change the input scale conversion factor for the LONGLIB metafile package. It may be called separately if desired. Only the metafile plotting package is affected. The routines RFACTOR and VFACTOR may be separately called to change the input scale conversion factor on the Ramtek and terminal packages, respectively. See FACTOR.
CALL PFACTOR (fac) fac (R): new conversion factor for coordinate values (only the metafile scaling is affected) <= 0 : scale factor reset to unity > 0 : new scale factor
