Why am I getting several coverage data points associated with my
    routine declaration when I do COVERAGE BY CODEPATH?

    Several languages generate prologue code at each routine entry
    to initialize the language specific semantics. As far as PCA
    is concerned, code is code and deserves code path analysis.
    This environment is usually set up by a CALLS or JSB to an RTL
    routine. PCA considers CALLS, CALLG and JSB to be transfers of
    control, because control does not in principle have to come back,
    and places a BPT in the instruction following.
