companies(3,1)=60 : companies(3,2)=2000
companies(4,1)=20 : companies(4,2)=1500
companies(5,1)=15 : companies(5,2)=300
CLS
FOR c=1 TO 5
PRINT "#";c;" Price ";companies(c,1);" quantity ";companies(c,2)
NEXT c

thank you and if you can please send it to realm_knights@hotmail.com
or post on these forums

hmm .. I'm not sure what you want to do, but ... for your first code :


for the second one :
1. if index = 0 then we don't read the inputs and others lines until the loop
2. it's done
3. it's done




if you have question, hask them in the forum

you are a life saver but i still need 1 more thing on the snd code i need it to loop then end the program if some 1 chooses 0 for any company

well I've edited your code and now it checks to see if the user pressed 0 and it only allows the user to enter numbers.

see the rem commands to see what I did.

Hope this helped.

ty very much you 2
