RE: what is unclear about 01 02 03 -Reply

Peter,

You point out one rule I have for using indicators. Set them and use them
with a couple of lines. The chain/leave code is a great example of this. As
long as I use the value of the indicator w/in a few lines of setting it
indicators can be very easy to understand and maintain. On the other hand,
if I set three indicators in mainline and 5 more in subroutines and then
test them in yet other subroutines then I am asking for trouble.

I may not be an old hand, but I *do* use lefthand indicators under
some conditions, especially when handling the results from an
operation that signals it's success or failure via indicators.
The rationalization is that the silly thing was set a line or two
above and thus, it's meaning and significance is not mysterious.
Lefthand indicators just seem cleaner somehow...
