Text to Speech with Events

For wine we have to install Sapi5, if not exist. To do this use this in linux terminal: winetricks speechsdk


The difficult part was the number and the wrap in screen. Text is written word by word as object sp (an SAPI.SpVoice) speak words. Scrolling happen normally after last line. Symbols like comma and parenthesis can't displayed (are not words).


Module UsingEvents {
      Form 60, 32
      Declare WithEvents sp "SAPI.SpVoice"
      That$={Rosetta Code is a programming chrestomathy site.
      The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another. Rosetta Code currently has 913 tasks, 214 draft tasks, and is aware of 707 languages, though we do not (and cannot) have solutions to every task in every language.}

Hunt The Wumpus

This is a simple implementation of the classic textual game Hunt The Wumpus.
First publish at rosettacode.org

Walk from one room to other, in a total of 20 rooms, to find the Wumpus Monster and kill it. Each room has three tunnels to link to other rooms. All rooms are vertexes in a dodecahedron.
There are two Giant bats, which always transport you to a random empty room. Also there are two bottomless pits which kill you; Also you have 5 arrows and if miss to kill the Wumpus then it is 75% a chance which he move to adjacent room. If you miss the last shot then you loose.
You can use H to toggle Help on/off. Help display player and wumpus position, the three tunnels and the number of each room for these, and the contents of rooms too. You can delete any information you desire in Sense() subroutine.

Rational Numbers Class

This is a Rational Numbers class and an example.
Rosetta code - 1st publishing
Using a part of this class to find perfect numbers
Another way to find perfect numbers using primes

Added pz as pointer to rational number. Operators works ok with pointers but return a new rational number not a pointer.
