Can I make unmodifiable product in Scilab?

[hill0093]

1) When I give a program I have written in Scilab to my client,
can I give a version that the client cannot read or modify?
2) When I give a program I have written in Scilab to my client,
does the client need to have Scilab installed in order to use it?

2. i think so. is there an option of creating executables?
