Field's modification of MemHandles

[Dana Long]

I'd like to better understand what Fields do to their MemHandles. For 
instance, I understand that they may grow the handle if it's too small 
to hold all the text but do they also shrink the handle when the text is 
deleted? If someone can point me towards a good reference I'd appriciate it.

As per suggestions for the masking of passwords typed into a text field, 
I am manually updating the field on a keydownEvent. I've allocated a 
memory handle of sufficiant size to hold the password and assigned it to 
the text field. On keydownEvent I StrCat the new char value to the end 
of the field's text either masked of unmasked. Can I assume that the 
handle I allocated is still being used by the text field or do I have to 
FldGetTextHandle() again and then check that the size is large enough to 
hold the next character?
