Why do we use lowcase function twicw while using SAS

eg:lowcase(lowcase(trim("    gsbls")));

[Reeza]

I don't think the double usage would change anything here. A single usage will suffice. 

[vinit_correia]

i saw an example,it was specifically written for only one string and all other strings in it were given only one...

eg:-

lowcase(lowcase(a));

lowcase(b);

lowcase(c);

[Reeza]

I'm not sure I understand your question. The double usage doesn't affect anything but doesn't accomplish anything. 

Is this code generated from SAS or user written?

[vinit_correia]

its a user written code

even i feel that it should not affect the outcome of the program 

but in other cases lowcase is mentioned only once...as i have shown above.only this one pirticular case its given twice

[Reeza]

Again what's your question?

If it's user written code feel free to change it and use only one.

Yes ,double usage of lowcase will not affect the result.However it may be a typo error if manually written.
