Okay, so my problem is I have to loops because I have different pages on my forward procedure. What I am trying to do is when I hit the 1 I go to inventory and go back to the menu by hitting any random button. When I hit 2 i go to Description of my items, but I have 12 items and I need to be able to go to their pages. But when I enter 'a' it brings me back to the menu. I tried putting them all in one loop but it won't work. I need to have the description choices a - l on the Description page so I can go to the description of each item. Please help. This problem is really confusing for me.




loop
var option : string (1)
menu
getch (option)
case option of
label "1" :
Inventory
label "2" :
Description
end case
end loop


loop
var option2 : string (1)
Description
getch (option2)
case option2 of
label "a" :
Rihanna
label "b" :
SHINee
label "c" :
BigBang
label "d" :
MichaelJackson
label "e" :
KellyClarkson
label "f" :
EP
label "g" :
KatyPerry
label "h" :
OneRepublic
label "i" :
MBLAQ
label "j" :
Adele
label "k" :
Infinite
label "l" :
Hedley
end case
end loop

You only need one loop. Do you know how procedures work?

I know that but I'm using a forward procedure and my teacher says that it is possible and I just have to figure it out. I have seperated my forward procedure into 4 different body procedures. The 2nd body procedure called Description needs to be seperated into 12 different body procedures. I need two loops so I can go from the menu to the description and from description to each of the different artists of the cds. It's either using loops or creating some kin dof "+" button to extend a list and a "-" button to shorten the list so I can just have one loop where I can access all of my descriptions. But I don't know if the second one is even possible, so I have to use the first one.

You only need one loop. Why don't you make a procedure to draw each screen. Say 'drawMenu', and it will draw the menu.

Then you could take input to the user, and do something like

Turing:

loop
get userInput
if userInput = 1 then
drawInventory
elsif userInput = 2 then
drawDescription
.
.
.
end if
end loop
