instructions:JMPNZ (jump to the given address if the
accumulator not equal to zero) RET(return from a
subroutine) ADB (add the contents of register B to the
accumulator and save result in the accumulator).

Answer / steve holton
As this is mainframe assembler section, this is a trick
question - there is no JMPNZ opcode for mainframe (recently
added JNZ with relative addressing in the z/800 and later,
but no JMPNZ) and the mainframe has no RET instruction
(there is a PR to return from a cross address space or PC
"call" statement) and the mainframe has no accumulator, ADB
opcode, or B register.
