   2 ! PR25039 This test checks that commas in input fields for formatted sequential
   3 ! reads are interpreted as the read completion.  If no comma is encountered the
   4 ! normal field width determines the end of the read.  The test case also checks
   5 ! that default blanks are interpreted as NULL in numerics.
   6 ! Test case derived from sample provided in PR by Iwan Kawrakow.
