To attach a descriptive label to a variable look at either

* the "setinfo" command or
* the menu item /Variable/Edit attributes (or select a variable
in the main window, right-click and Edit attributes).
 
yes, but i referred to a value labels (for example sex= 1-male; 2-female)

Look up the "xtab" command.  It can do cross-tabulations for
several variables, if that is what you're looking for.
 
there are any function to obtain a table with layer's variables?
 
Thank you very much.
