On the one hand, each array access requires a small amount of overhead to run
the key through a hash to find the value's address. However, that overhead is
pretty small...
No, no - the meat here is this:
do makeAccessVars("vi", line 1 of tTSVdata)
...
repeat for each line tRec in tTSVdata
vs
repeat for each line tRec in tTSVdata
put explodeRow(tRec, tColumnNames) into aData
I wouldn't care to hazard a guess as to the relative speed of "aData[x]"
versus "item x": but it's the overhead of the function which creates the array
on that I don't want to pay *on every row*.
