+# If record length is to be set or increased, the unit is SZ_REAL even
+# though internally the unit is SZ_CHAR.
+#
+# Phil Hodge, 30-Sep-1987  FIO options added.
+# Phil Hodge, 15-Nov-1988  Remove option to set buffer size.
+# Phil Hodge,  8-Apr-1993  Modify for short by including TBL_ROWLEN_CHAR.
+# Phil Hodge,  5-Oct-1995  Include check on file type when setting table type.
+# Phil Hodge,  7-Jun-1999  Add table subtype; delete TB_F_TYPE;
+#		use SZ_FNAME instead of SZ_LINE for error message.
+# Phil Hodge, 11-Jul-2003  Return without doing anything when called to
+#		change the table type of STDOUT or STDERR.
