NPIECE
Type:  Adverb (Scalar)
Use:   Specifies the number of pieces of something.
Null value:  0 => 1.

Tasks:
   FITAB.........Writes data in FITS format to tape and disk.  NPIECE is
                 used to break uv files into several separate disk/tape
                 files for reliability and space purposes.  NOTE: uv
                 data are written as FITS tables and can be read only in
                 15APR99 and later.
   FITLD.........Reads FITS files to load images or UV (IDI or UVFITS)
                 data to disk.  NPIECE gives the maximum piece number to
                 read from a file broken into "pieces".
   MORIF.........Combines IFs or breaks spectral windows into multiple
                 windows (IFs).  NPIECE controls the number of of IFs
                 The current data are divided into or combined to.
   PCFIT.........Finds delays and phases using a pulse-cal (PC) table.
                 NPIECE sets how the IFs are combined to compute the
                 delays.
   PRTTP.........Prints the contents of data tapes and FITS disk files,
                 using NPIECE to specify multiple disk files as pieces
                 of a uv file as written by FITAB.
   SNSMO.........Smooths and filters a calibration SN table.  NPIECE
                 tells SNSMO how the IFs were combined in FRING's delay
                 solutions.
   UVLOD.........Read export or FITS data from a tape or disk.  NPIECE
                 gives the maximum piece number to read from a file
                 broken into "pieces".
Procedures:
   Y2KSAVE.......Verifies correctness and performance using standard
                 problems.
