Digging through functions

I'm digging around in various functions, to see what might be left over and interesting.
I stumbled on this. Does anyone have any ideas as to what it's intended to do?
Code: Select all
on revVerboseDebug pWhat
global gREVVerboseDebug
set the cVerboseDebug of stack "revPreferences" to pWhat
-- setting this 'cause its going to crash, so save now
-- MM-2011-03-13: [[ Bug 10073]] Make sure the stack file version is maintained at 2.7 for backwards compatability reasons
revInternal__SavePreferences
set the cVerboseDebug of stack "revPreferences" to pWhat
set the messageMessages to pWhat
put pWhat into gREVVerboseDebug
if pWhat then
delete file "verboseLog.txt"
open file "verboseLog.txt" for text write
end if
end revVerboseDebug

The fact that '2.7' is mentioned suggests that is a fairly ancient bit of code.
or rather the role it seems to perform there makes me think of the 5 levels in HyperCard:

It was the line:
Code: Select all
-- setting this 'cause its going to crash, so save now
that got my attention.

In the light of that line of code you wonder why the whole thing was left in the IDE and not removed.

Presumably . . .
Code: Select all
set the cVerboseDebug of stack "revPreferences" to pWhat
pWhat is a variable, so the first thing has to be to find out if verbose debugging can have parameters.

Queer, as as far as I can understand debugging is either verbose or not, and verbose debugging is not something that admits of degree.

pWhat is passed either a true or false,
on revVerboseDebug pWhat - It's the rest I'm wondering about. Perhaps ties into something in the revPreferences stack or the engine itself.
Seems to dump whatever it would be to a text file. Of course, there are varying levels of verbosity.
I don't know what relevance that image above has to do with anything, but it just means yet more scrolling for someone following along
