// Sept. 19/96: Modified to use "strtod" to do floating point
//              conversions (Avoids need to use MS Service Pack 1).
// Sept. 23/98: Increased SetPrecision to 6 - part of conversion to
//              WIN32 - conversions handled differently.
// Jan. 28/99:  Alter Lat/Lon conversion to use mmddd.ddd format.
//              (LatLonData=TRUE means data is Lat/Lon).
