do "N" bytecode

[Pastyl <pastyl5@...>]

I have a question. Is there any way to start, stop and then start it again?
I need to compile a program in lua, then execute 100 the user to do
something in C, and again to perform 100 instructions from lua, and
again to do something in C program in lua is free.
Something like lua_do100bytecode (L)
