Well, character(kind=1) is the default character kind (1-byte ASCII)
that you know from F77.  Fortran 2003 added support for other character
sets, such as ISO_10646, which uses 4 bytes/character and is therefore
represented by kind=4 in gfortran.

4_'ABC' is the literal "ABC" in this character set, etc.

The program in comment#0 works just fine. It prints AABABC.

Right, Fortran does not use zero terminated strings,
I think Martin changed the way how non-printable characters are output,
the new output might be more correct, but maybe it swallows the
final \x00 since that is not a null-terminated string in fortran.

But, I admit, when I initially learned fortran, F77 was still brand new.
Can someone explain to me what is this program is supposed to do?

IIRC Bernd changed this.  IIRC fortran strings are not NUL terminated.
