The GCC COBOL compiler now accepts a file descriptor (FD) name as a parameter to the CALL statement, a nonstandard extension. Currently, it interprets this as a buffer name with a warning, or an error without the ‘-dialect ibm’ option, beginning to address mainframe semantics. A new __funcsig__ macro is also introduced for debugging.
