Finding a string of data in a variable

gstover — Thu, 23 Jun 2022 20:06:14 GMT

I am trying to find a specific string of data in a variable to set a new variable and am having major issues.

Here is the code:

string_find = find(indicators, "Educational") ;

if string_find ^=0
then notes='Educational';

This is not working. I am going crazy, please help!

Example data where that is not working.

Some likely issues: your value is a different case than "Educational" such as "educational" or "EDUCATIONAL" or some different combination of upper and lower case letters. If this is the case then add the option "i" to the Find function symtax to make case insensitive comparison:

string_find = find(indicators, "Educational",'i') ;

Having the information you provided, it is hardly possible to help (except for the pointing that all compares in sas are case-sensitive, if you don't use options disabling this), so: Please post data in usable form an the complete step you have written to process the data.

This is the what is in the variable indicators:

Exam matched indicator flag;Signed by Attending;PACS transfer complete;Clinical;EMR transfer complete;Completed

When I use the following code it marks this record as 'Educational' and it is not.

data qpath_us ;
retain MRN CSN full_name exam_type date attending signatory institution indicators notes covered_exam discat ;

length discat $10.
notes $60. ;

set &dsn1 (drop=accession qa_status operator reviewer gender rename=(account=CSN patient_id=MRN)) ;

if CSN ne . ; /*remove temporary ids*/

if put (csn,wq9639l.) = '@#%'
then notes='9639' ;

if put (csn,wq9640l.) = '@#%'
then notes='9640' ;

billing_provider = left(upcase(attending)) ;

if put(exam_type,$examfmt.) = '1'
then covered_exam = 'Y' ;
else covered_exam = 'N' ;

if find(exam_type,'Procedural')
then discat = 'PROC' ;

else

select (exam_type) ;
when ('ED Abdominal Aorta') discat = 'AORTA';
when ('ED FAST Exam') discat = 'FAST';
when ('ED Focused Chest Ultrasound') discat = 'ECHO';
when ('ED Focused Echo') discat = 'ECHO';
when ('ED Renal Ultrasound') discat = 'RENAL';
when ('ED ULTRASOUND EDUCATION') discat = 'EDUCAT' ;
otherwise discat = 'ALL OTHER';
end ;

new_indicators = upcase(indicators) ;

if find(new_indicators, "EDUCATIONAL")
then notes = 'Educational';

else

if exam_type = 'ED ULTRASOUND EDUCATION'
then notes = 'Educational' ;

else notes=notes ;

if notes = 'Educational'
then covered_exam = 'E' ;

run ;

Thanks

I am not that bored to create dataset &dsn1 and fill it with guessed values. That would not make any sense at all. So until you post an excerpt of the data you have, it is difficult to help. The unformatted code you have posted makes reading it unnecessary difficult, too. You should add do...end to the if statements and add some put-statements, to know which assignment sets "notes" to "Educational". See orange text in your code.
