Hi Everyone,

I am wanting to create a variable that tells me whether the patient has an ICD10 starting with E11. I am not interested in the numbers after the dots, nor am I interested in any of the other ICD10 codes and I am wanting to drop patients who do not have E11 in one of the ICD10 columns. I have tried playing with foreach, but this side of things is new for me and I just keep getting messages telling me the syntax is incorrect. I would greatly appreciate any hints someone could give me, thank you in advance.
