The  FMS/UPGRADE command converts FMS V1 form files or form libraries
  to  FMS  V2  data structures. Entire libraries or single forms can be
  converted.  Valid FMS V2 forms are created, but, the names may not be
  compatible  with  the  FMS  V2  utility  functions.   Names  are  not
  restricted  to compatible Common  Data Dictionary format. The default
  input file type is FLB  and the default  output file type is the same
  as the input file type.

  Example:  FMS/UPGRADE/OUTPUT=V2LIBRARY V1LIBRARY

      The entire form library V1LIBRARY.FLB is converted
      to the Version 2 form library V2LIBRARY.FLB.
