| Input T, T is the Top of the range. |

INPUT T |
| Select a random number between B and T Rand generates X where 0 < X < 1 and since we are truncating we need top to be 1 higher. In other words if our range is 0 to 10 (T+1) - B = 11, if rand returns .00..01 our output is close to 0 and will be 0 once truncated. If rand returns .999..9 our output will be near 11 and will be 10 when truncated therefor all our numbers will be represented with nearly equal frequency. |

RTN |
| The 'TRY HIGHER' and 'TRY LOWER' subroutines are seperate from main program flow because the program needs to clear the stack before showing the messages if this doesn't happen the correct number will briefly flash on the screen before or after the pause is executed. Both of these subroutines just clear the stack display the appropriate message and then return to the main subroutine execution. |
