Base Register is the register, acts as a address holder of
the base storage location from where the datas were stored
continuously. Assembler uses the Base register value to
find the data that is required.

Answer / divya
base register is used to assign a relative address to all
instructions and storage areas. By adding the address in
the base register to the displacement of the instruction,
we can find the absolute address of the instruction.

A register that holds an aboslute address from which the
address of other statement (instruction) or data storage
can be calculated. In other word, a general register from 3

register.

Answer / joseph louis pargas
A base register is any general purpose register chosen by
programmer. It is assigned at the beginning of the program
as part of housekeeping with the USING assembler keyword,
and it's purpose is to maintain addressibility within a
page (4k) of code or data.

Base register also used for Automatic updating. In many
applications there is a great deal of data movement between
CPU and memory. Therefore it is very useful if the base
register(r11) is updated in each load or store.

In the house keeping section of an MVS assembly language program, like the one below STM R14,R12,12(R13) BASR R12,R0 USING *,R12,R11 LA R11,2048 LA R11,2048(R11,R12) .... .... 1. What if BASR R12,R0 IS NOT PRECEDE USING *,R12,R11? 2. USING (base address), REGISTER does USING directive says assembler to treat particular Register as a base register with the mentioned base address..in the above case * i.e current location counter..well if that is the case why we need BASR R12,R0 ? 3. What if I write like STM R14,R12,12(R13) BASR R12,R0 LA R11,2048 LA R11,2048(R11,R12) USING *,R12,R11 there is no address resolution being calculated in both LA statements so is it a right way to set Base register?..will there be any issues with Domain regarding R11 and R12?
