         * imach.c (Module): Error in rewriting the 'r' file with yearsfproj or yearsbproj fixed          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
 2022-04-05  Brouard Nicolas  <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
         * imach.c (Module): Fixed covariates (dummy or quantitative)          results.  The most important work consisted in retyping the Brent
         with missing values have never been allowed but are ERRORS and          original PRAXIS program written in Algol W (published with errors,
         program quits. Standard deviations of fixed covariates were          ommitting the transposition of matrix V before its QR reduction
         wrongly computed. Mean and standard deviations of time varying          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         covariates are still not computed.          The awe library had errors, for example in arc tangent function
           which have been fixed.
 2022-03-17  Brouard Nicolas  <brouard@ined.fr>  
           The main objective was to get identical results with the three
         * 99r25 Improvements in fixing discrepancies between covariates          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         missing in result line but in model.          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
 *Wed Mar 31 2021  Nicolas Brouard   <brouard@ined.fr>  
         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
         * ./ (Module): Fixed bug on result:          '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
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
           seen that authors while trying to mimick original Brent Algol W
         * imach.c (Module): Fix bug on quitting after result lines!          code are hesitating by changing either a loop originally from 1 to
         (Module): Version 0.99r21          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.
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          the original Algol W arrays. Thus the X(I) is translated in C as
           x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          minimum of parameters in the functions calls, as it is in Algol
         and life table from the data without any state)          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * version.h: Summary: version 0.99.r19          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
         * imach.c: Summary: Projection syntax simplified          useless. Gegenfürtner used a lot of static variables or functions
         We can now start projections, forward or backward, from the mean date          which I tried to minimize. Also in Gegefürtner, array dimensions
         of inteviews up to or down to a number of years of projection:          were fixed to N. In my adaptation the flin is static double
         prevforecast=1 yearsfproj=15.3 mobil_average=0          flin(double l, int j) and the parameter used are global variables.
