PROGRAM TEST_IO

! actual data not important

[EMAIL PROTECTED] test_blas]$ ./a.out

109
12
109
-----------------------------------------------------------------
As you can see this is the expected normal behavior, but if you redirect the
output by either piping to something like less, or to a file then editing with
say:
[EMAIL PROTECTED] test_blas]$ ./a.out > junk; vi junk
the file becomes:
12
[EMAIL PROTECTED]@ 109
12
[EMAIL PROTECTED]@^@ 109
------------------------------------------------------------------
the ^@ characters are supposed to be the blanks that the #X outputs. As you
can see it prints some odd character instead. This only happens after you
make a newline with /, otherwise it works as normal. If you have a single
format statement with multiple /2X statements like format 101 above, the first
one works correctly, all others after this exibit the bug.
