st: Is there a way to replace a variable with a missing value without knowing if it is numeric or string?

["Gupta, Ani" <agupta@compasslexecon.com>]

I have a series of variables, - say name, age, position, startdate - some of which are numeric and some of which are string. I want to replace their values with missing values if another variable, indicator is equal to 1.

In other words I want to be able to write something like this:

foreach var in name age position startdate {
	replace `var' = _missing_ if indicator == 1
}

Is there a way I can do this in a single loop for numeric and string variables?
