"The string variable is a code with values such as 0107, 0256, etc.
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?
