Hi Abhishek,

Please use <code> tags to format your code and example input. See also How do I post a question effectively?

A first quick analysis is that your problem seems to stem from the use of the Switch module - its use is discouraged, please see the section "Limitations" in its documentation. If I replace the switch statement with next if /^[*\/]|simulator\s+lang|^include/i;, your code appears to run the same no matter the order of the subroutines.

There may be other possible places for improvement, I haven't read the code in detail yet, but that seems to be the main problem.

Hope this helps,
