I don't understand how to access in a front end the arguments to the -I option on the command line.
Cobol has a feature similar to the C preprecessor, known as the Compiler Directing Facility (CDF). The CDF has a COPY statement that resembles an #include directive in C, and shares the property that COPY names a file that is normally found in a "copybook" which, for our purposes, is a directory of such files. The name of that directory is defined outside the Cobol program. I would like to use the -I option to pass the names of copybook directories to the cobol front end. A bit of exploration yesterday left me with the sense that the -I argument, in C at least, is not passed to the compiler, but to the preprocessor. Access to -fmax-errors I think I've figured out, but -I is a mystery. I'm a little puzzled by the status quo as I understand it. Unless I missed it, it's not discussed in gccint. ISTM ideally there would be some kind of getopt(3) processing, and the whole set of command-line options captured in an array of structures accessible to any front end. Is that not the case and, if not, why not? Many thanks. --jkl
