How can I make it numeric without loosing the "0" in front? 

In other words I want to keep all the digits."

 

You can't really "keep" the digits in a numeric variable, but you can 

control how to display the values with -format-:

  destring strvar , generate(numvar)
  format numvar %04.0f

 

If strvar is "0007", numvar is 7, displayed as 0007 in a list.

 

Both these commands will do the same thing:

  summarize x y z if numvar==7

  summarize x y z if numvar==0007

 

Was that an answer to your question?
