-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)".


Hope it helps.

Dear All,
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.
