HFPRT: Prints out selected HF table entries
INNAME Main input file (name).
INCLASS Main input file (class).
INSEQ 0.0 9999.0 Main input file (seq. #).
0 => high
INDISK 0.0 9.0 Disk unit #. 0 => any
INVERS 0.0 9999.0 Inversion of HF table
PRTLEV Print Level. 0-> inext
1-> solutions, 2-> dump
DOCRT -3.0 132.0 Output control
OUTPRINT Output file name
BPRINT 0.0 99999.0 Beginning row to print
EPRINT 0.0 99999.0 Last row to print: 0 => end
Use: This task reads the HF files associated with the FRING
MBDLY and CL2HF programs. It writes the data at
several detail levels.
INNAME......Main file name (name). Standard defaults.
INCLASS.....Main file name (class). Standard defaults.
INSEQ.......Main file name (seq. #). 0 => highest
INDISK......Disk drive # of image. 0 => any
INVERS......Input extension file version #.
PRTLEV......The level of the print out. 0-> Index
1-> Basic solutions
2-> Dump of HF file
DOCRT......False (< 0) use the line printer if OUTPRINT = ' '
else write named OUTPRINT file only.
When OUTPRINT is not blank, DOCRT=-2 suppresses the
page-feed character on page headers and DOCRT=-3
suppresses page headers and most other header
True (> 0) means use the terminal interactively.
The task will use the actual terminal width as a display
limit unless 72 < DOCRT < width. In that case, the display
limit will be DOCRT characters.
A wide terminal is recommended for this task.
OUTPRINT...Disk file name in which to save the line printer output.
' ' => use scratch and print immediately for interactive
jobs - batch jobs use OUTPRINT = 'PRTFIL:BATCHjjj.nnn'
(jjj= job #, nnn = user #). When OUTPRINT is not blank,
multiple outputs are concatenated, and the file is not
BPRINT......Beginning row number to be included .
EPRINT......Last row number included. 0 = highest.

Program HFPRT writes out the HF file which is created by
CL2HF. This file mimics the 'Format 52' fringe files which
are created by MK3IN and the Haystack correlator. This is the
data which is converted by HF2SV into a format which can be
read into Calc/Solve.
The output of HFPRT with PRTLEV=1 contains the basic output from
the correlator and can be used for further analysis.
The format of the HF table (the following is copied from MK3IN)
