Hi Jim,

just advertising for a package I happen to maintain
(rather loosing than earning money with that):

what about giving up array and use lineno.sty (alternatively:
numline.sty) instead (CTAN: macros/latex/contrib/lineno)?
Together with the Standard flushleft environment?
In this way, you could get automatic line numbers
in the left-hand margin and do in the rest whatever you want.

However, as often, in writing I am thinking more deeply:
What is the problem with the array environment?
What about \begin{flushleft}\begin{array}{rl} ?

longtable or supertab my be preferable to array since
a listing doesn't fit on a single page.

[I waited a while with posting; it still may be appropriate.]

HTH -- Uwe.
