Last time I saw indirect addressing was on the 7094. That machine was storage constrained and had no "general registers".

Instead of branching to the address pointed to by the second operand, it uses the second operand as the address of an 8 byte area which contains the address to which to branch. I guess this is sort of like an LG combined with a regular BCR. A nice way to implement branching via a branch table. -- UNIX was not designed to stop you from doing stupid things, because that would also stop you from doing clever things. -- Doug Gwyn Maranatha! <>< John McKown ----------------------------------------- The information contained in this communication (including any attachments hereto) is confidential and is intended solely for the personal and confidential use of the individual or entity to whom it is addressed.
