*
*::>          VERSION  4.24/00   05/05/95 11.48.44
*
*
*    New patch FPCLASSC by Francois Dardare. This interfaces to the
*    system routines on the various platforms that identify the
*    IEEE NaNs (where appropriate), and classifies them in a general
*    way. The routines are called in HFILL, HFN and HFNT2 to check
*    user arguments, and warnings are issued where appropriate.
*
*    New routine HNFORM for assiting users in creating the character
*    string that describes CW nTuple variables that is used as an
*    argument to HBNAME or HBNAMC.

*
*
*::>          VERSION  4.23/01   22/02/95 14.34.06
*
*    New user routines HIJE and HXYE for returning errors on cells in
*    2D histograms a la HIE,HXE.
*
*    New routine HBVERS in the C patch, that returns the version string.
*
*    Some error checking and extra calls to HBUG in the HFNT tree.
*
*    Modification to HCX to fix a bug produced when the routine was
*    called with option 2 (get error) for a histogram without the
*    required bank.
*
*    Extra argument IOPT added to HCXY in order to allow the caller
*    to specify whether the contents (IOPT=1) or the error (IOPT=2)
*    on the given cell is returned.
*
*    Bug corrected in HROUT. Problem was appearing in case of many
*    subdirectories. Variable NLCDIR was not correctly set when returning
*    to the parent level.
*

*
*    Introduce DOUBLE PRECISION in HCX for Profile histograms
*
*    Adjust HREBIN to allow for non-equiwidth bins.
*
*::>          VERSION  4.23/00   05/11/94 09.36.29
*
*    HLDIR with CHOPT='N' works now also for disk directories.

*
*::>          VERSION  4.22/14   14/10/94 12.20.44
*
*    Due to some early design mistake PAW expects all character columns to
*    be returned in character*32 variables instead of in variables of the
*    original size. For single character variables this was fine, however
*    character array columns were not restored correctly (unless they had
*    an original size of 32). To fix this HBOOK has to know if the Ntuple
*    is read back by PAW. Bit 3 in the status word of the first block is
*    set in this case (in HBNAM). HGNT2 and HGNTF check this bit in case
*    of character arrays. Routines modified: HBNAM, HGNT2, HGNTF, HNTGET,
*    HRIN.
*
*::>          VERSION  4.22/13   28/09/94 08.40.30

*
*    Many decks indented.
*
*    New option in HLIMAP.
*    When the first parameter LIMIT=0, an existing shared memory
*    is attached as the current directory. In this case, HLIMIT must have been
*    called before.
*
*    Changes in HDIFF to solve numerical problems (precision).
*
*    Extend range of formats in HINDEX and HINPRX.
*
*    Bug corrected in HRESETM1 and HREZ0M in case of profile histograms
*    or histograms with error bars (bug reported by W.Brueckner)

*                 with chains.
*
*    Routine HBALLOC: pass also first event (to define event range).
*
*    Routine HGNT1: accepts dynamic buffer offsets as argument (used by
*    HGNTBF).

*
*::>          VERSION  4.22/02   19/05/94 12.07.56
*
*    Several changes in patch HMCSTAT (Christine Beeston)
*    >1) I've fixed the bug with the number of entries - I now use HSUM instead
*    >of HNOENT to get the number of entries in a histogram, since including
*    >the underflows and overflows messes up the normalisation of the result.
*    >
*    >2) The user can now do multiple simultaneous fits (this was requested and
*    >seems useful) - to do this they must call HMCINI once for each set of
*    >histograms (each fit will have a data histogram and a set of monte carlo
*    >and weight histograms), and then
*    >HMCLNL must be called with the histogram identifiers and number of MC
*    >sources, as well as the fractions.
*    >
*    >HMCMLL already uses the new HMCLNL, I have left the old HMCLNL as HMCLNO,
*    >but will delete it in a couple of months.
*    >
*    >HMCINI and the new and old versions of HMCLNL both contain a banner
*    >announcing the change, as it's not backwards compatible.
*    >
*    >The weight histograms may be used for more than one of the
*    >fits if necessary - a check is made to make sure that they are not
*    >normalised more than once.
*
*    Minor change in HRENDC (nchmax=nchtop before loop)
*
*    Mods in HMINUT to compute an equivalent chisquare in case
*    of a log-likelihood fit
*
*    Bug fixed in HPAK in case weights <1.e-5 (number of entries was wrong)
*
*    Protection in HREND (NCHTOP was changed in the loop)
*
*::>          VERSION  4.22/01   07/04/94 09.04.32
*
*    Bug corrected in HFC1 in case of empty histograms with one bin only
*
*::>          VERSION  4.22/00   30/03/94 09.53.07
*
*    Bug fixed in HBOOKN (IQ(LCIDN+5) set to ID) for disk-resident tuples

*
*
*     Histogram directory bank LTAB created and MZPUSHed with 500 words

*     New deck HNDESC in patch HNTUP
*     Corrections in CWN filling and GET routines for character type columns
*
*     Ulrich Mueller changes for IEEE computers in filling routines.
*     There is an unpleasant feature in HBOOK on computers with IEEE 754
*     floating point arithmetic (in our case on DECstations under Ultrix
*     4.3a, CERNLIB 93b or 93d).
*
*     Calculations on these machines can give as result Infinity or
*     Not-a-Number (NaN). If one tries to fill these numbers into histograms
*     (and this happens in real-world applications, especially during the
*     development phase of a program), some problems may arise:
*
*     1) Filling of +/- infinity as value. This case is handled properly by
*        the checks for over/underflow and the value is counted as such.
*
*     2) Filling of NaN as value. The over/underflow checks fail because
*        relations like .LT. or .GE. are always false if one of the operands
*        is NaN. Then the value is converted to a bin address, which is an
*        undefined integer and finally results in either a segmentation
*        fault or an overwriting of memory somewhere.
*
*        However, this could easily be fixed, for example in HF1 (the other
*        routines are analogous):
*
*           IF(X.LT.Q(LPRX+1))THEN
*              ICHAN=0
*           ELSEIF(.NOT.(X.LT.Q(LPRX+2)))THEN
*              ICHAN=IQ(LPRX)+1
*           ELSE
*              ... calculate bin address ...
*           ENDIF
*
*        By changing the overflow check from .GE. to .NOT. .LT. the NaN
*        value will be counted as overflow. Another approach would be a
*        separate check for NaN, something like
*           IF (.NOT. (X.LT.0. .OR. X.GE.0.))
*        together with an appropriate error message.
*     ====>      This changes has been made in all filling routines
*
*     3) Filling of Infinity or NaN as a weight. This is maybe the worst
*        case. The value is added to the bin, and this results in a crash
*        when the ZEBRA structure is written to a file, or in a crash of PAW
*        if one tries to plot the bad histogram.
*
*        I propose to add a check for the finiteness of the weight. On most
*        machines a (C-)function "finite" is available for that purpose.
*     =====> This suggested change is not yet implemented.

*      If successful, the new header is written to the file
*      Header of CWM Ntuple is written the first time a content buffer
*      is written. The header is written again whenever a column has
*      been added to the Ntuple. After every HFNT2 call that caused
