OK.  The function is STR$CONCAT.

somewhere VMS pre-V8.*, where it's WRONG, WRONG, WRONG...

#define  str$concat  STR$CONCAT
#ifdef __NEW_STARLET
unsigned int str$concat(
        void *destination_string,
        void *source_string);

and later VMS versions, where it's workable,...

#define  str$concat  STR$CONCAT
#ifdef __NEW_STARLET
unsigned int str$concat(
        void *destination_string,
        void *source_string_1,
        __optional_params);


Now, if you can include <str$routines.h> and make this go away, I'm wanting.
