The type of pBoxtemplate is ^word.
Is it not true that
  (dword(pBoxtemplate) and 1)=1
evaluates to TRUE, if and only if pBoxtemplate is NOT aligned to a word 
boundary (16 bit boundary)?

And then, assuming pBoxtemplate is aligned to word boundary, is it not 
true, that
  if (dword(pBoxtemplate) and 2)=2
evaluates to TRUE, if pBoxtemplate is NOT aligned to a dword boundary 
(32 bit boudary), causing the statement
  if (dword(pBoxtemplate) and 2)=2 then inc(pBoxtemplate);
to make the pBoxtemplate align to a dword boundary (by eventually adding 
2 to pBoxtemplate (because sizeof(word)=2)??
