6.2 Maximum Line Length

Most other implementations of SCCS also have an upper limit on the maximum length of line that can be handled in a text file (that is, those versions of SCCS which have such a limit do not apply this limit for binary files). To set such a limit in CSSC, use the --enable-max-line-length=N option to "configure". This sets the limit to the specified value.

If CSSC is adding a new delta to an existing file, and it finds an input line which is longer than N characters, if will fail with an explanatory message (the alternative would be that an SCCS file would be generated that could not be read with other versions of SCCS).

If, on the other hand, CSSC is creating a new SCCS file in response to the admin -i command, one of two things will happen when an over-length line is found. If binary file support is enabled, the SCCS file will automatically be created as an encoded file. Otherwise, admin will fail with an explanatory message.

This setting can be overridden with the environment variable CSSC_MAX_LINE_LENGTH; for a description of how to use this environment variable, see 7. Environment Variables.
