You can run the Header-to-copy utility directly from the command line or invoke it automatically using the PREPROCESS(headers) Compiler directive. The Headers preprocessor allows C header files, with an extension of .h, to be specified in a COPY statement in a COBOL source file. The preprocessor recognizes these as C header files and uses the Header-to-copy utility to convert them. This can be very convenient for relatively small header files.
To invoke the Header-to-copy utility from the command line, type:
h2cpy {[filename] [option]} ...
where the parameters are:
| filename | The C-language header file to be converted to a COBOL copybook |
| option | An H2cpy command-line option |
If you do not specify filename or option, a list of available options is displayed.
