Dear Paul,

No trick will be never possible. The user can always use fun2string to 
display the source code of any function that Scilab can execute after 
reading it from a .sci file. You cannot prevent Scilab for doing so.
Scilab can be executed in a mode where it displays each line of code 
before executing it.
The user can also modify Scilab source code to get Scilab display 
whatever Scilab is allow to read. If Scilab can execute it, Scilab can 
display it. This is completely unavoidable.
