This comment make me think you are expecting the Scilab console to 
know about xa when running your function liczSL. You should probably 
read about variables scoping here:
http://wiki.scilab.org/howto/global_and_local_variables

Anyway your description is unclear and not complete.
After running the code with Tcl instructions in it I get a GUI. What 
am I supposed to fill in the blanks and what am I supposed to do with 
the GUI menues to reproduce your error?


> /function []=liczSL()/
> /  global('wlxa','wlya','wlxb','wlyb','wla','wlb')/

This global is not needed (and potentially harmful).


> /'proc calcSL {} {'/
> /'ScilabEval liczSL()' /
> /'}'];/

This is not returning any result. How do you expect this to fill in 
your blanks "Punkt wcinany" (I don't speak your language) ?

Try to add the required Tcl_SetVar in function liczSL
