The concept of the C runtime (aka ANSI C library) regarding errors during
writing on files is to keep the application alive and to provide a function to
check for such errors, that is ferror. This behaviour should be the same on all
platforms, that's what portability is all about. And so I think the developers
of LE (which is today's name of the former C/370 runtime) did it right when they
catched the B37 and other file related abends and continued execution. Of
course, you always have some performance penalty when you fit the I/O subsystem
of a particular opsys to the needs of a programming language or the given
semantics of a library.

Kind regards
