Dear Joao, I do beleive that the SetLength only resize the array, ie: The Vetor has 3 elements like:
Vetor[0]:= 1 Vetor[1]:= 2 Vetor[2]:= 3 And then eu want the same variable but with only 2 element, then SetLength(Vetor, 2) Vetor[0]:= 1 Vetor[1]:= 2 As you can see you don't lose the first 2, After that you want 4 elements on the same variable: SetLength(Vetor, 4) If you print the variable, before associate any value to it you will get: Vetor[0]:= 1 Vetor[1]:= 2 Vetor[2]:= 0 Vetor[3]:= 0 Hope it helped Lourival 2007/10/31, Joao Morais <[EMAIL PROTECTED]>: > Marco van de Voort wrote: > >> Adrian Maier wrote: > >> VArray: array of TSomeClass; > >> begin > >> SetLength(VArray, 10); > >> // now you have VArray[0] ..
