Hello, I just started coding in ada, so I have problems, esp. with string 
handling since it's much different from C or pascal style... I'd love to 
see an example of expression parser (like getting "2+2" string and giving 
integer=4). I also know that string in ada is saved as (first,last,*text) 
but I don't know if there's any simply method of changing first and last.
thanks for any help, regards
Marcin
