Bob, nothing bad would happen as long as you only ever pass a pointer. 
(Either a declared pointer field or %ADDR of something else.)

But OPTIONS(*STRING) allows you to pass character data directly, without
%ADDR.  If you passed a character field expecting it to be used as the
input buffer, then the compiler would copy the field + x'00' to a
temporary, then pass the address of the temporary.  The temporary would
get updated, and the character field would retain its old value.

The inBuffer parameter should just be prototyped as * VALUE, without the
OPTIONS(*STRING).
