[fpc-pascal] Access Violation When SetLength(DynArray, Value)

[James Richters]

I only recently learned about using Low() and High() and it is so much nicer
than 
For I:= 0 to Length(MyArray)-1 Do

That I actually went though all my code replacing the Length() - 1's with
High()

I still end up with a lot of 
SetLength(MyArray,Length(MyArray)+1); 
Every time I want to add one more thing to the array.

Almost all of my  dynamic arrays do this, because I can only add one thing
at a time to the array... and the reason I wanted it to be dynamic in the
first place.  

Is there some nifty way to increase a dynamic array by 1 that is more
elegant?  
Inc(MyArray); would sure be nice
