      (Module): Comments (lines starting with a #) are allowed in data.
   This program computes Healthy Life Expectancies from  
   cross-longitudinal data. Cross-longitudinal data consist in: -1- a    Revision 1.108  2006/01/19 18:05:42  lievre

   the model is: log(pij/pii)= aij + bij*age+ cij*sex + etc , where  
   'age' is age and 'sex' is a covariate. If you want to have a more    Revision 1.104  2005/09/30 16:11:43  lievre

   The advantage of this computer programme, compared to a simple    health status (= 1-p13= p11+p12 in the easiest case of somebody in
