When there is a read statement expecting a single entry and a single
comma is entered, the read expects more input.
The test program is:
stuff = 1
stuff2 = 2
write(*,'(1x,a,$)')'Enter 2 somethings: '
read(5,*)stuff,stuff2
write(*,'(1x,a,$)')'Enter something: '
read(5,*)stuff
call exit(0)
end
[ashtray] image 205 % gfortran -o inputbug inputbug.f
[ashtray] image 206 % ./inputbug
Enter 2 somethings: ,,
Enter something: ,
,
/
[ashtray] image 207 %
It does not accept a , as a default entry for a single number, although two
commas work when two numbers are expected. Once it gets one comma it even
refuses a / until a second return is entered.
This happens on Fedora Core 4 with gcc-gfortran-4.0.2-8.fc4
and on Mac OSX 10.4 with gcc version 4.1.0 20051026 (experimental)
