Sorry, I forgot to mention it. The data showed below is only small part
of it. This data file contains 28 columns: location, year, month, and
day, + each hour. There are 72 locations, and a location contains data
with 2192 rows. Therefore 2192 * 72 = 157824 rows total.
The error message was:
DATA INT = Array[28]
REFORM: New subscripts must not change the number elements in DATA.
Execution halted at: TEMP1 27
D:\MODIS_Documents\MetData\IDLPractice\temp1.pro
It seems that IDL reads only first rows.
What do you think? Do you have any suggestions? Thanks.
