/* ZRTADR -- Return the program address from which the routine calling zrtadr
* was called. If zrtadr is called in procedure B and B is called from
* procedure A, the address returned by zrtadr will be the address in A
* following the call to procedure B. This can be used to determine which
* procedure called B.
*
* This is a portable stub for the actual routine, which is machine dependent
* and normally written in assembler.
