Bug #: 55991 Summary: Support or document "Escape Sequences" Classification: Unclassified Product: gcc Version: 4.7.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: damage3...@gmail.com Sun Studio's f77 support an extension called "Escape Sequences". (P34, FORTRAN 77 Language Reference) It is very similar to the escape sequences of C-like languages. http://en.wikipedia.org/wiki/Escape_sequences_in_C I definitely hope that GNU Fortran can support this feature also. In case it is still non-standard and you don't want to support it for any reasons, can you document it in "Extensions not implemented in GNU Fortran"? I hope this not a duplicate and thank you in advance.
