Right. To be more specific,

For example, suppose you wish to standardize all the variables. You'd do:

foreach var of varlist q1-q5 {
egen std`var'=std(`var')
}

HTH,
John.

Dear Statalist,

Maybe that's a silly question, but Google didn't give any answers:

I want to create a loop with foreach over ALL variables in a dataset,

foreach ALL VARIABLES {
...
}

It is not possible to write

foreach var1-var100

because the number and names of the variables vary from dataset to dataset and the do-file has to work for any dataset without making any changes.


Thanks a lot.


Best wishes,
