status.i4.v = str_insert_char_c(string.i1a.r, length.i4.v,
					insert_position.i4.v, insert_char.i1.v)

	This routine inserts a character in the middle of a string.

	string		string to have character inserted into it
			(Note: This buffer must be long enough to hold
			 the present string plus the additional character.)
	length		length of "string" (If a value of zero is passed,
			the length of the string will be calculated.)
	insert_position	position in string to insert the character
			(starts at 1)
	insert_char	character to insert into string
