Answer Posted / sysprog

The assembler directive START establishes the beginning of the program, and the operand 0 means an offset of 0 from the beginning of the module. If a program uses an instruction before using BALR to establish a program base register, the program base register will be offset from the beginning of the module, by the length of the instruction that precedes the BALR. Using START with an operand of that length can be useful for a more perspicuous assembly listing. START with a non-zero value is also sometimes used in 24-bit programs that due to their length being great enough to necessitate it, make use of more than one program base register; however, in most such situations, the CSECT assembler is used.
