layout problem

[Γιώργος Κοσμίδης]

Thanks for your answer.
The lines where as you asnwered me.
When I post my mail the layout was tottally ruined.
Here I post the program again but I have replaced all spaces with
underscores ( _ )
This is the error that I have:  ERROR "c:\textanalysis.HS":48 - Syntax error
in declaration (unexpected `->')
Thanks in advance for all the help that you can give me
