Hi Chris,   I know this is a super old thread but I wanted to ask about using SAS prompts for conditional processing and it was the most relevant one that I could find, plus you also seem to know about this!   I have an EG project which is a collection of all the week end processing code that we run. I wanted to add some additional code that is only required at month end. I already define a macro variable "month_end" as 1 for the weeks we class as month end and 0 otherwise. I am then using this to conditionally process the month end code:     My question is around the format of the condition that I am creating as I can't quite understand how this works. I created this on my own PC but the project is run by a number of other users as well. When I initially created the condition, I filled in the box like this (or without the & and . on the macro variable name, I think I tried both):       However, that didn't seem to work on my PC and, after a bit of research I added quotes around both the macro variable and the value and it seemed to work. However, when my boss then ran the project it didn't work for him, the condition failed every time and nothing ran. I then changed back to the above on his PC and for some reason that worked.   I have no idea what is going on with this. Firstly, do you know which format is correct? Secondly, is there any reason this would differ between two PCs, both, I believe, on SAS EG 7.1?   Also, as I have more than one bit of month end code, I read that the flow stops when a condition is failed and downstream code does not run. I have not found this to be the case and have had to add the same condition to all relevant bits of code.   Any help on this would be very much appreciated.   Thanks,   Steph ... View more
