Qbasic/QuickBasic Programming

With my previous program, Collatz Conjecture.exe, (https://qb45.org/files.php?action=showfile&id=1976), using certain rules showed that with any positive integer, a meandering path of integers would always end up at "1". Now with this program, Reverse Collatz Conjecture.exe, instead of ending up "downstream" at "1", by using different rules it is possible to travel through various junctions where different forks can be chosen by the user which results in different meandering integer paths "upstream" with the same starting integer. If the final "upstream" integer is plugged into Collatz Conjecture.exe, the same meandering path is followed "downstream". The zip file contains the Windows executable, the source code, and a PDF with screen shots that fully explain the new "upstream" rules with examples.
