One more Pascal related question.  When should I call the following?

var   p:pointer (or StringPtr, or anything pointer)
begin
....
new(p);
....
end;

In other words, when do you have to call new()?  Only when it is defined
in 'var' headings?  Only global 'var' headings?  How about as value parameters
of a procedure/function?  I was writing a program that kept crashing 
(corrputed string) until I called new(mystringptr).  But I have made
other programs before that do similar things and I never used new().  I
am confused.  Someone please help me.

Thanks

Never test for an error condition that you can't handle.
