Trailing space removal using strip function

Babloo — Tue, 10 Sep 2019 08:04:57 GMT

I'm trying to remove the trailing spaces with the use Strip function as follows, but it is not removing the spaces in the final Output.

Am I missing something?

FNCTL_CMPNT_NM=strip(ifc(indexw("&etls_jobName","_ADP_"),'AP','LIS'));

My Value for FNCTL_CMPNT_NM is 'LIS ' after the execution of the above code.

I assume the "final output" is what gets into variable FNCTL_CMPNT_NM

With SAS character variables being of type CHAR you will always have strings padded up with blanks up to the length of the character variable so there are in a way always trailing blanks. Nothing you can do about it except to define the variable with a length not longer as you really need it.

Hello,

Imagine putting a small item in a large drawer. It won't reduce the size of the drawer.

The same happens here : you affect a small string to a previously large dimensioned string

so FNCTL_CMPNT_NM will contain the stripped string and the rest will be filled with blanks.
