I don't know specifically about COBOL, but calls from C to
many other languages expect the address of, not the value of,
the arguments.  For arrays that happens sort of automatically
(an array name is a constant pointer to the first element),
but not for scalars.  Try an & in front of the non-array.

(Maybe %ref would also work.)
