CodeString objects supply a ".lineof" method for this.
And I think that PGE (or perhaps PCT) automatically promotes
the target string into a CodeString.  So from a Match object,
one can typically do:

    .local pmc orig
    orig = match.'orig'()
    $I0 = orig.'lineof'(1000)     # get line number for position 1000
