REPORT procedure: uninitialized variable in a COMPUTE block

Kevin_Viel — Fri, 22 Jan 2021 17:52:16 GMT

I am struggling to understand an issue about an uninitialized value in a variable that I use in a COMPUTE block that does not have a missing value. I have used this approach before. I got the hint on this board from Cynthia Zender. If I change to a character version, no issue are reported and the report is formatted as intended.

8748  data __folder_transferred ;
8749    set __folder_transferred ;
8750    levelc = put( level , 8. -L ) ;
8751  run ;

8758    column ( "Section II. Files Transferred" "`{style [ fontweight = medium backgroundcolor  = lightgrey ]Provide file information below (e.g., package names, individual file names, sizes, etc.).}"
8759             group level file size units
8760           ) ;
8761    define group / noprint order ;

As you can see, the data step does not report a missing value. The second REPORT procedure, a copy of the first with LEVEL replaced by LEVELC, runs without issues.

Does anyone see what I am overlooking?

Thank you,

Kevin

After I posted, the ORDER option to the DEFINE statement caught my eye. Adding ORDER to the DEFINE statement for LEVEL resolves the issue. I will not have a think about the process 🙂
