If statement did not work?

[ybz12003]

Hello,

I would like to make the change in the code shown below.   'uairway' and 'ulungoth' are numeric; while 'uairwayothsp', 'Ulungothsp', and 'record_updated' are the character. 

data want (keep=ulungoth Ulungothsp record_updated uairway uairwayothsp);
	set have;

	if caseid in ('EUJK009') then Ulungothsp='CHRONIC RESPIRATORY FAILURE, BIPAP DEPENDENT' and ulungoth=1 
									and record_updated='Yes' and uairway=0 and uairwayothsp=' ';

	if caseid in ('EUJK009');
run;

The log window showed the massage below:

NOTE: Character values have been converted to numeric values at the places given by: (Line):(Column).
236:48
NOTE: Numeric values have been converted to character values at the places given by: (Line):(Column).
237:76
NOTE: Invalid numeric data, 'CHRONIC RESPIRATORY FAILURE, BIPAP DEPENDENT' , at line 236 column 48.

Then, I didn't see any change in the result I want in the (ulungoth Ulungothsp record_updated uairway uairwayothsp) columns.   Where did I do wrong and how to fix it?  Thanks.

Please show us the entire log for this data step, including the code as it appears in the log, as well as all NOTEs, WARNINGs and ERRORs. 

From now on, please do not show us errors detached from the code that caused the error.

Unless you want a dataset of identical rows... I guess you may want something like this:

data want (keep=ulungoth Ulungothsp record_updated uairway uairwayothsp);
	set have;

	if caseid in ('EUJK009') then do;
		Ulungothsp='CHRONIC RESPIRATORY FAILURE, BIPAP DEPENDENT';
		ulungoth=1;
		record_updated='Yes';
		uairway=0;
		uairwayothsp=' ';
		end;
run;

i.e. to execute many statements when a condition is true, you need a DO END group.

Awesome, thanks much!

This expression:

'CHRONIC RESPIRATORY FAILURE, BIPAP DEPENDENT' and ulungoth=1 
and record_updated='Yes' and uairway=0 and uairwayothsp=' '

is a logical expression which will be true if ulungoth = 1, record_updated = "Yes", uairway = 0 and uairwayothsp is missing (empty string). The first part (a non-missing string) is always considered "true".

The result of a logical expression is numeric and either 0 (false) or 1 (true). If the variable on the left side of the assignment is not already defined, the data step compiler will implicitly define it as numeric.

I keep getting an error message every time I run the code. I went over it with my TA and assumed everything was correct but I keep getting error message. 

This is the error message I get; ERROR 180-322: Statement is not valid or it is used out of proper order.

Please help the assignment is due tomorrow!!
