         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
 2021-03-08  Nicolas Brouard   <brouard@ined.fr>          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
         * ./ (Module): Fixed bug on result:          results.  The most important work consisted in retyping the Brent
           original PRAXIS program written in Algol W (published with errors,
 2021-02-20  Nicolas Brouard   <brouard@ined.fr>          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
         * imach.c (Module): Fix bug on quitting after result lines!          The awe library had errors, for example in arc tangent function
         (Module): Version 0.99r21          which have been fixed.
   
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
   
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          'normal' mathematical arrays starting from 1 to n. But this is a
           real issue in C where, by default, arrays are starting from 0 to
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
         and life table from the data without any state)          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
           shifting the index from original X(I) in Algol W to x[i-1] in C.
         * version.h: Summary: version 0.99.r19          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c: Summary: Projection syntax simplified          the original Algol W arrays. Thus the X(I) is translated in C as
         We can now start projections, forward or backward, from the mean date          x[i] which minimizes the errors. The Golub QR algorithm was
         of inteviews up to or down to a number of years of projection:          published in Algol with overflow errors which were reproduced in
         prevforecast=1 yearsfproj=15.3 mobil_average=0          Brent's Algol W code. Buckhardt code fixed these errors which are
         or          much more problematic in C than in Algol W.  Thus Buckhardt code
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          seems very safe, but i haven't chosen it for IMaCh because the C
         or          style is horrible and almost unreadable compared to Gegenfürtner
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          CO code which is very close to Brent's original. Also what makes
         or          Buckhardt code more difficult to read is, instead of passing the
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
         * imach.c: Summary: doxygen tex bug          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
         * imach.c: Summary: There was some wrong lines added          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          flin(double l, int j) and the parameter used are global variables.

         The number n which was limited to 20,000 cases is now unlimited, from firstobs to lastobs. If the number is too for the virtual memory, probably an error will occur.          * imach.c (Module): In the ILK....txt file, the number of columns
           before the covariates values is dependent of the number of states (16+nlstate): 0.99r46
