If the variable is numeric
replace x = x*10 if x<100
(trusting that you really do only have 2- and 3-digit positive values, so anything less than 100 is a 2-digit value)

or, if the variable is string,
replace x = x + "0" if length(s)==2

Hi,

I have a variable which has 2-digit values and 3-values. I would like
to change all 2-digit values into 3 digits by adding a zero. How can
I do this? Thanks.

Raoul
see example below

the list of values looks like this:

12
148
456
21
364
390

and I would like to add a zero to the third and fourth values.
