FMX - excluindo os não múltiplos de um numero

 

No post anterior criamos um programa, que apagava

todas as ocorrências dos múltiplos de um número,

neste aqui faremos ao contrário,

apagaremos todos os não múltiplos de um número

dentro de uma matriz de inteiros de dez mil elementos.

acompanhem no vídeo  seu funcionamento por favor:
