In this question, I rename the numeric variable phone to
numphone and then try use phone=put(numphone,comma16.) to
store the numeric value numphone as a string value in phone.
But I get a warning tha numphone already exists and in the
data sat phone doesnt exist and numphone is set to missing. Why?

data names_and_more;
input Name $20.
Phone : comma16.
Height & $10.
Mixed & $8.;
Name = tranwrd(Name,' ',' ');
rename phone = numphone;
phone = put(numphone,comma16.);
datalines;

Yes you are right.

The way you coded tells the compiler to do two actions
simultaneosly on the PDV. The renaming will be done once
the data step is closed.

data t;
set names_and_more(rename=(phone=numphone));
phone = put(numphone,comma16.);
run;

In the above example which uses the same data that you
gave, this works the way you wanted. Dataset options work
on the dataset not on the PDV.
