Equally, knowing the solution from first principles is also always
worthwhile.

" I can't think of any good reason not to use -renvars-"
Neither can I: I did not want to imply that -renvars- is not a good
command,
just to set the record straight re -replace- and show how you can
achieve
the same result from first principles.
Nick Cox
What's more, as well as doing completely the wrong thing the -replace-
call here would be illegal unless the variable in question were a string
variable.
I can't think of any good reason not to use -renvars- when
renvars, lower
is a complete solution to the problem named.

-replace- would change the values of the variable, not its name. If
Rajaram
does not want to use -renvars-, as suggested by Richard, he can of
course
say
foreach var of varlist _all{
rename `var' `=lower("`var'")'
}
" some of them are numeric and some are string variables."
The storage type of the variables should have no bearing on this
operation,
as all you want to change is the name, not the values. If ever you
wanted to
condition on the type, use -ds-, as in my

Suppose the variable is named x, try "replace x=lower(x)".

Is there any way I can change the name of the variable. In my data set
the variables are in capital letters and I want them to change into
small letters. There are about 700 variables and I wanted to change
them into small letters. The list of some of the variables in my data
set is given below, some of them are numeric and some are string
variables.
S1Q1 wanted to change to s1q1
S1Q2 change to s1q2
S1Q3 change to s1q3
S1Q4 change to s1q4 etc.
