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