Thank you very much!
I found the book:

Do you know any other reference about function and sub implementation,
using bison/yacc/etc.?

One is not doing that way, trying to make the parser jumping. Instead one
builds a parser tree or "closure" using the actions, which is executed
after the parser has been terminated (or finished suitable parsing blocks).
There was a thread here recently "speed-up parsing"; check the Help Bison
