Very true, and I think it would be better if [loop-last] worked like Mike
describes with automatic interpolation of ITL within
[loop-last][/loop-last].

Thank you Paul and Ed for that code.  It does work in the example I gave,
but the point of having [loop-last] based on a scratch value is that a
scratch value need not only be based on the number of times the loop has
iterated.  [loop-increment] could be used for that.  In the code above,
"listing_counter" will be incremented each time the loop iterates no matter
what, right?  That doesn't allow you to use a conditional statement to
increment "listing_counter" or not.  It looks like that's just not possible?
