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

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

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);

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?

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

Again what's your question?

 

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