Oh, dear. :-(
It is OK to use loops within loops if you have to, but I see no evidence
that you have to do so in anything you have told us or in this code. I
can't even figure out where the number 637 comes from. Doesn't the size
of your loop depend on how many files you have to open?
I would write something along these lines:
filelist = file_search('*.*.h29v07.005.*.hdf', Count=count)
array = StrArr(count)
FOR j=0,count-1 DO BEGIN
Catch, theError
IF theError NE 0 THEN BEGIN
void = cgErrorMsg()
Print, 'Bad File: ', filename[j]
Message, /Reset
Continue
ENDIF
thisFile = filelist[j]
hdf_id = hdf_sd_start(thisFile)
...
ENDFOR
Cheers,
David
