/*
 ** NAME
 **   init_fra_data - initializes all data from the FRA needed by FD
 **
 ** SYNOPSIS
 **   void init_fra_data(void)
 **
 ** DESCRIPTION
 **   Counts the number of retrieve jobs in the FRA and prepares
 **   an array so that these jobs can be accessed faster.
 **
 ** RETURN VALUES
 **   None.
 **
 ** AUTHOR
 **   H.Kiehl
 **
 ** HISTORY
 **   10.08.2000 H.Kiehl Created
 **   17.01.2024 H.Kiehl Print out the number of remote directories
 **                      here, so we always can see how this value
 **                      changes, without restarting FD.
