1. If you use TRACE INSTRUCTION in conjunction with the PSWA option, only
instructions within the range of the address specified by PSWA are traced.
2. You may use the DATA option to limit tracing to certain instructions or
sequences of instructions. For example, trace instr data 183f causes the
tracing of all LR 3,15 instructions; the command trace instr data 183f50
traces all LR 3,15 instructions only if they are followed by a STORE (ST)
instruction.
