Hi,
I hesitate to give the easy answer, but what the heck. IDL can do
string math so the following works a treat.
dateString = '970625'
newDateString = '19' + dateString
But if you really need to do date math then you need to split the string
into a 2-digit-year, a month and a day using STRMID. Add the century
(1900) to the 2-digit date. Then you run the while thing JULDAY before
doing math on it.
Cheers,
Ben
