Dica de If para verificar variável com valor

Normalmente quando desejamos verificar se determinada variável tem algum valor, usamos um If da seguinte forma:

If FC VAR ALFA is not equal to BLANK And
FC VAR ALFA is not equal to NULL
End If

Quando a variável é numérica o If fica ainda maior:

If FC VAR NUM is not equal to BLANK And
FC VAR NUM is not equal to NULL And
FC VAR NUM is not equal ZERO to
End If

Esses Ifs podem ser substituídos por um bem mais simples:

If FC VAR ALFA is greater than BLANK

Pode também ser utilizado para campo numérico... façam os testes !

If FC VAR NUM is greater than BLANK

Se quisermos verificar se a variável está em branco, é só mudar o comparador lógico.

If FC VAR ALFA is less than or equal to BLANK

Pode também ser usado para variável numérica, que tem valor inicial = 0 (zero)

If FC VAR NUM is less than or equal to BLANK

Bom trabalho !!!
