corrupt stack symptoms

[Byron Turner]

I experienced a freeze a week ago but everything seemed fine after that 
until today.  Suddenly today my script wouldn't compile and it flagged 
as errors unchanged elements of my stack script.  After commenting out 
those elements it flagged other unchanged element  one after another  
including very simple elements (example below).  I could comment out 
the whole script and it compiles but that's not very useful.  What 
could cause this? if its a corrupted stack, are their any fixes? As 
this is a substack, do I need to scrap everything and start fresh or is 
there some method for determining the damaged elements?
