A conditional trace system in a computer system for controlling the enablement of a trace operation in the computer system, the computer system including a set of instructions for operating said computer, the set of instructions including branch instructions, the branch instruction generating a jump signal whenever the branch instruction performs a branch operation, the conditional trace system comprising a conditional trace field in each branch instruction where the conditional trace field has either a first or second value and a first means responsive to the value of said conditional trace field and the jump signal for selectively enabling and disenabling the trace operation within the computer system. |
