ISUS FILENAMING


ISUS data files are saved internally only as a sequential dive (ie cast) # 
For example:	DIVE082.DAT

Once downloaded, they are renamed to included the date and a cast (or cal) number
Same example:	DIVE082_091007_03.DAT


THERE ARE EXCEPTIONS :
BETWEEN DIVE130 to DIVE154 no renaming was done but date is inside file.
