start_code - Start code

The start code contains local variable definitions for the function implementation. It is suggested not to define local variables in the code section, but in the start section, only. On the other hand, the start section should not contain code lines except the code for initializing variables.

Note, that the start code is outside the try/catch block for functions that have enabled try_catch. Thus, initializing code in the start section must be 100% save.
