hi all i am trying to learn more about macros and  this below is the 1st problem i was doing: When i run the code i do see in the logs that a data set gets created but it dont get the output so i figure it is something with the macro code but dont know what. Also eventhough i have the mprint option i still dont see in the logs that the macro processor resolves the sas statements and  that is probabloy cuz something's wrong with the macro code? Please help options mprint; DATA orders; INPUT CustomerID $ 1-3 OrderDate DATE7.
