Betreff: st: sort of standardization

Dear Statalist,
I have to standardize many variables (in order to run PCA).
Besides generating the n corresponding std(varname) vars, which I have
already done, I also want to generate n new  variables obtained dividing
each variable by its range. Can anybody help me?
