Hello, I am Base SAS Student. I'm trying to do a Combining Various Boolean Operators but I was get some error to execute this below code. First I had making New Database then I tried to combine data with using Boolean Logic. I tried using this code but it didn’t work As an example, the data set Medical contains information on clinic, diagnosis (DX), and weight. A program to list all patients who were seen at the HMC clinic and had either a diagnosis 7 or 9 or weighted over 180 pounds demonstrates how to combine various Boolean operators: Data Learning_From_Medical; Length Id $ 3 VisitDate $ 10; Input Id Clinic $ DX Weight VisitDate; Cards; 001 HMX 18 220 05/08/2006 003 TDX 8 265 02/06/2006 005 HTX 20 285 04/04/2006 004 HMC 9 185 25/07/2006 025 TFT 7 272 28/06/2006 032 HMX 12 160 18/02/2006 065 TDX 28 289 16/03/2006 072 HTX 32 255 12/09/2006 099 TFT 44 112 09/09/2006 050 HMC 88 198 12/12/2006 065 HTX 120 250 02/07/2006 002 HMC 7 162 20/11/2006 008 TDX 65 277 15/08/2006 012 HMC 12 222 14/04/2006 006 TFT 6 666 06/06/2006 ; RUN; Title "Example of Boolan Expressions"; Proc print Data=learning_from_medical; where Clinic eq 'HMC' and (DX in ('7','9') or Weight gt 180); id ID; var Clinic DX Weight VisitDate; Run; Can someone please give me the exact code to solve this error? Thanks!
