how to find whether string1 is in the string2 or not?

blueskyxyz — Tue, 21 Apr 2020 11:32:24 GMT

Hi ,

My code wants to find whether string1(smq) is in the string2(AEDECOD) or not?

which doesn't work normally, why? how to change the code?

************smq list***********

SMQ

**bleep** fissure haemorrhage

**bleep** haemorrhage

**bleep** ulcer haemorrhage

Anastomotic haemorrhage

Anastomotic ulcer haemorrhage

......

garbage code displays above, update as following:

%let smq=**bleep** fissure haemorrhage/**bleep** haemorrhage/**bleep** ulcer haemorrhage/;

I'm afraid I'm having trouble understanding the problem, and what you are trying to do and what the desired results are. Could you take a simple example or two or three and show what the inputs are and what the desired output is?

at the moment since there are no matching values the macro returns a dataset with zero observations. so please update the macro variables values to below and run the macro so it returns a dataset with 4 observations.

%let smq=Anaemia|Diarrhoea|Insomnia;

@BrianVarney Brain, thanks for your reply.

In my code, I also use the same mehod.
