OpenCOBOL uses program names for different two purposes: file name and
function name.  If you write a statement CALL "address@hidden", then open-cobol
will try to find a file "address@hidden" and call a function address@hidden' in 
it.
The function name can be anything in this case.  What the programmer
wants is to call the module "address@hidden".  The function name is not visible
to the programmer.

Now, we don't do any conversion with file names.  What I am thinking
about is the function name, which is part of the internal call convention.
Since function names are restricted to C names, I just wanted to encode
them.  (Yes, this might be confusing, but I think is acceptable.)

With open-cobol you can do something like this:

  int (*func)();

  func = cob_resolve ("address@hidden");
  if (func)
    func (...);
  else
    /* error */

The run-time function `cob_resolve' does everything you need, including
function name encoding if necessary.
