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

Subject: interesting, to me, new z14 instruction: BIC

Branch Indirect on Condition. 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.
