Os ciclos são usados para executar um determinado pedaço de código tantas vezes quantas as que estejam dentro de determinadas condições que definimos.

Mas vejamos os seguintes exemplos do ciclo While:

 

Nestes dois exemplos, o ciclo é executado até que se atinja o último registo de uma determinada base de dados. Neste caso o pedaço de código que nos informa se o ciclo deve terminar ou não é o RS.EOF, que nos indica se já chegámos ou não ao último registo.

While executa as declarações dentro do seu ciclo enquanto uma dada condição seja verdadeira. No momento em que se torne falsa, o ciclo pára. Lembrem-se de terminar a declaração While com a palavra Wend.

Uma variante do ciclo While que testa condição depois do ciclo é o Do Loop.

 

Neste caso o ciclo Do Loop Until é executado até que a variável i atinja o valor 10.
