Well, my comment was meant to try to get those that swear profusely that common blocks are a
Bad Thing to explain why. I place common blocks in the same category as GOTO statements - if
used incorrectly they can lead to unbelievably bad source code that may or may not work.
However, used correctly and judiciously they can greatly simplify the code - for both the
programmer and subsequent user/readers. Having dealt with particularly blech f77 code replete
with common blocks (anonymous, named, different lengths, etc.) I can sympathise with those that
despise common blocks but, to use a building analogy, it's not the hammer's fault when the
framing for the house falls down....

I even use them in Object programs!!! :o)

No argument there, but sloppy programming can cause problems regardless of what construct one
uses to manage variables, memory, etc. Pointers are what come immediately to mind..... with
objects a close second.
