### 6.1 Binary File Support

Binary file support can be turned off when you run “configure” by specifying the `--disable-binary` option. This will cause `admin` to refuse to create an SCCS file whose “e” flag is set (see Flags). The `admin` program would normally do this if the user requested it via the `-b` option or if it discovered that the file could not safely be stored in the normal SCCS file format.

This setting can be overridden with the environment variable `CSSC_BINARY_SUPPORT`; for a description of how to use this environment variable, see Environment Variables.

If you use CSSC with support for encoded SCCS files turned off, encoded files will still be handled; CSSC will just refuse to create a new one. This provides as great a degree of interoperability with other implementations of SCCS as possible.
