*     alphabetic character (A-Z)  - a variable definition record.      *

*  All dates in the file are represented by century month codes (cmc). *
*  The century month  code is defined  as the number of months  since  *
*  December 1899 and is calculated as follows:                         *
*                       cmc = 12*year + month                          *
*  You can convert from cmc to normal calendar dates like this:        *
*                       year = (cmc - 1)/12                            *
*                       month = cmc - 12*year                          *
*  To  compute the length of time in months  between any  two  events  *
*  subtract the cmc of  the  first  event from the  cmc of the second  *
*  event.                                                              *
