Hi, Nigel:


The "super-macro" is quite a lengthy chunk of program, so tracing thru
it is going to be bit of a task.

IAC, I think this will initially be a needle-in-a-haystack troubleshoot
.... at least until I have run the macro a few dozen more times to build
up enough empirical evidence to speculate on a culprit. Since the macro
can take up to an hour to complete -- per worksheet -- this may take a
while.

Thx for your reply!

can
cause problems.

It is unlikely to be 'random' , although it may appear to be! - try
setting
up the same start conditions and run the code again, put a conditional
watch
in to check for value changes that are invalid, and also use breaks to
halt
code execution at the appropriate place.

Chunk up you code into more manageable blocks - maybe it is the same
sub-routine causing the problem - check each using the above approach.

Hope the above helps. Good luck.

I'm having some reliability issues with a "super-macro" I'm
currently
using. This macro -- which calls on several sub-macros -- is quite
process-heavy and operates on worksheets that often have thousands
of
rows. Much of the "processing" involves search and replace or search
and delete. E.g., replace "&" with "and".

Unfortunately, the "super-macro" will randomly miss a replace or
delete. The problem does not crop up frequently, but the results do
cause problems with programs this worksheet ultimately interfaces
with.

I have removed speed-optimizing code which I thought may be a
culprit.
I.e.:

Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
[ your code ]

Application.ScreenUpdating = True
Application.Calculation=xlCalculationAutomatic

But the reliability remains unchanged.

Any info on how I can improve reliability is appreciated!
