Procedure Problems

[ipwnuha]

What is it you are trying to achieve?
Text adventure game with procedures.


What is the problem you are having?
I need to call upon procedures but am having problems with them not being declared. is there a way around the "procedure not declared" problem?



Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)
This is the code i am using

Turing:

var choice, key1, key2, sword: int sword:= 0 key1:= 0 key2:=0 procedure east cls put "You enter the room and look around startled you turn around and see the door behind you close better hope there is another way out!" put "Choose the number of what you want to do" put "1. open door" get choice  if key2 = 1   then put "you leave the room, and see the outside and the sun. goodjob you have completed this adventure!"  elsif key2 = 0   then put "you aproach the door and see a lock. you try everything in your inventory but fail. You later starve."   put "GAME OVER" end if end east procedure north cls put "After heading north you enter a small room, you catch site of a key" put "hanging on the wall, however you also notice a BEAR. it is sleeping" put "Choose the number of what you want to do" put "1. Go south" put "2. Attack the bear" get choice if choice = 1  then center elsif choice = 2  then if sword = 0   then put "You hurl yourself at the bear punching it wildly. it turns and slowly devours   you whole."    put "you are dead"   elsif sword = 1    then put "you sneak up on the bear and hit it with the sword, it does no damage, the bear trying to impress somone eats your sword then turn on you, it soon dies of internal bleeding. good job! You grab the key off the wall and head south"    center2 end if end if end north procedure center cls put"You find yourself in a very simple room. there are corridors leading to the" put"north, south, east and west. The brick is plain and you see nothing" put"worthwhile near you." put "Choose the number of what you want to do" put "1. Go North" put "2. Go East" put "3. Go West" put "4. Go South" get choice if choice = 1  then north elsif choice = 2  then  east elsif choice = 3  then elsif choice = 4  then else put "I dont understand"  center end if end center center

Please specify what version of Turing you are using
I am using version 4.1 for turing

Aditional note. this is my first post and i am sorry for any formatting problems.

The problem is that you have procedures that call each other in a circular way. To do this you must use forward to declare the header for the procedure before declaring the body. Later in the code you can use body to declare the body of the procedure.

Example:

Turing:

forward proc P2 proc P1 P2 end P1 body proc P2 P1 end P2 % P1 calls P2 which calls P1 and the cycle repeats

Thank you very much that fixed everything.

unlikely to actually happen if you require user input in every procedure, but in long-enough games you run the risk of stack overflow exception (as there is no tail-end recursive call optimization -- that is, you just keep on building up a stack of new procedure calls on top of each other, never exiting from them).
