Dear Renata,
You are making the classical mistake of thinking tha macro code is
interpreted and runs where it is called within SAS code. Nothing is less
true. Your macro Amostra runs already _before_ the PROC IML code. It does
not assign the calculated value of IML variable Quantidade to the macro
variable Quantidade, but just the text 'quantidade' (without the quotes)
itself. If it concerned a SAS data step (can't you use that?) I would
recommend calling the macro from a CALL EXECUTE statement.
But like David C. already suggested: your code possibly can be corrected and
reduced if you tell us what you are trying to do at the higher level.
Regards - Jim.
