     Can you help me? Is there any package that will be more simple
     for this purpose? 

Indeed the lexer is very specific to PSPP, and rather unintiutive.   I
wouldn't even try to use it for any other purpose.  

If you want a general purpose lexer, then I would suggest Flex. 
http://www.gnu.org/software/flex ---  If you also need a parser then
you could look at Bison http://www.gnu.org/software/bison  although
the examples you gave may be simple enough that a hand written
recursive descent parser will suffice.
