Hi. I am quite new to SAS and would like to know if the following is possible and, if it is, how it can be done. What I am needing is a dialogue/message box (alla VBA) that pops up when, for example, a missing field is encountered during a data step. The box will inform the user of the specific error and give the user some options: Ignore error and continue, Exclude the missing fields, Abort the data step. The appropriate action will obviously be taken, depending on which button is clicked. Any help would be greatly appreciated. I am running EG3 although I do have access to EG4. Is there any info out there on what can be achieved in the way of message boxes?
