VFACTOR 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 terminal plotting package is affected. The routines PFACTOR and RFACTOR may be separately called to change the input scale conversion factor on the metafile and Ramtek packages, respectively. See FACTOR.

fac (R): new conversion factor for coordinate values
