Subject: st: foreach

I have data that is coded as "si" or "no".  I need to change this to numeric variables.  I tried the following but keep getting an error message that says, "varlist not found". Can anyone tell me what I am doing wrong?

Here is the code:

foreach x in varlist p03a01 p03a01a-p03a01m {
        gen y = (`x' == "si")
        replace y = 0 if (`x' =="no")
        drop `x'
        rename y `x'
        }

Thank you in advance,
Marilyn.
