Thx cherepets. I got blank screen again however. I really don't know, what's goin on. I think i'm doing something wrong with installing it.

Be default i have my 1,91kb in \MIDletPascal 3.1\Libs\ AND in \res\ folder of my project AND i added it to resources menu in program. This is the only way to make it work.

When i replace the lib_keys in /res/ folder by any other - i got got blank screen.
When i replace the file in \MIDletPascal 3.1\Libs\, then the program doesn't even compile.

I have no damn idea, what to do.
