6.2 Executable File Support

The support that cssc provides for binary files allows the controlled file to contain any sequence of bytes. That doesn't imply that the controlled file is used for any particular purpose. For example, JPEG files can contain non-ASCII acharacters.

This should be contrasted with support for executable files, which have a specific Unix file mode bit set (see the manual page for chmod for more details). Unix executable files may or may not be binary files. It's common to control shell scripts with cssc, for example. Shell scripts are normaly executable but not binary.

If the x flag is set, cssc will generate a g-file whose execute bits are set. This feature exists for compatibility with SCO OpenServer's sccs. Do not use this feature if you wish to interoperate with other implementations of sccs. Setting this flag with admin -fx generates a warning about this.
