You may want to repost your example data in a code box opened by using the forum {i} menu icon.
as posted when I copy the data to a text file your column 23 has the letter B for the first data record which is not valid for the TEMP variable as numeric.
Sometimes the forum main window "helps" by reformatting text and may have removed sequential spaces or possibly tabs.
This may be a starting example. I reformatted the data in the editor to better match the input descriptions. The numerics are defaulting to best. formats which look like integers.

If you want the values from the header record to be one the data records add a RETAIN statement listing the header variables of interest. I also created a datetime variable as putting date/time information together is often better than the separate fields. Note though that if any of the incoming values are not valid dates, ie month=2 and day=31, then the datetime is going to through an error about invalid date.
