Call Scan Function Error with Substring

[mglogan]

Hello,

I am using call scan to substring a variable to remove the last number from the string. I am receiving the Note: Invalid error to substring, although it seems to be working.

Have:

 

Want:

here is my code:

call scan(_egtpt, -1, pos, length) ;
egtpt= upcase(substr(_egtpt,1, pos-2));

LOG:

Any help with clearing the note would be appreciated. Thank you!

Can you post an example of the error with the log notes? That usually helps with determining what the issue is a lot quicker.

Yes! updated post with image

If your variable value has just 1 digit value as the last value, you don't need call scan

want=upcase(substr(k,1,length(k)-2));

[novinosrin]

Try

data w;
k='Pre-Dose 2';
/*call scan(k, -1, pos, length) ;*/
want=upcase(substr(k,1,length(k)-2));
run;

None of your examples generate an error with either your code or novinsorin's. I suspect you have some blank _egptpt entries and those records may be throwing an error.

Thank you! there were a few missing values. Works great now!

If you copy code and/or error messages directly from your log you can paste the text into a codebox opened using the forum's {I} icon. Then edit anything you don't want to show such as XXXX for sensitive data. I think this may be easier than creating an image file, editing the image and the pasting the image in the forum.

Then we can also highlight or otherwise indicate directly in the text where a problem may be.
