in thread subroutine function

Regarding question# 2 i believe now you do understand about dot(.); so first dot(.) is to concatenate left side variable. and right side dot(.) is to concatenate right of that variable. If string or variable is not available then it will simply ignore.

    No. "If a string or variable is not available" then it is an empty string or undef and an empty string will be concatenated (not simply ignored).
