I'm not familiar with RCS, or SCCS for that matter. I do use SCCS for one purpose which I find to be very useful, and that is to be able to let error functions report the module and line number of an error. Example in I4gl code: call catastrophy("%M%(%C%) ",sqlca.sqlcode) When the source code is submitted to SCCS, %M% is expanded to the name of the module containing the code, and %C% is expanded to the line number. So, when the catastrophy function is called like this, the module name and line number of the calling function are passed as a text string. This is VERY useful for debugging. I don't know if RCS can do this, and in practice I don't use SCCS for anything else. John H. Frantz
