Hi all,

How do I specify more than one criterion for commands such as tabulate/
histogram ?

Can one do "-if inlist" twice for say, tabulate?

If not, how does one go about specifying two (or more) criteria in a
command?

Do you mean, how do you use the and and or operators? See -help if-. Examples for the help:

. list make mpg if mpg>25 & mpg<30

This restricts the list to those cases where mileage is greater than 25 but less than 30.

. list make mpg if mpg>25 | mpg<10

This selects cases where mpg is either greater than 25 or less than 10.
