My problem is Error proofing my program!!!
You see, I want my program to catch numbers and other different command's that would normaly make the program crash, and I have no clue of how to do that. Could someone help me please or at lease post an tutorial on how to error proof properly.

Thank You

firstly there are a lot of tutorials on error proofing but if u can't read them then i'll just give it to u. this is a function that the error proofing is written in and all u have to do is call it in your main program where u ask the user to enter something and it will work. put this on top of your program.

code:

% function to find a valid integer function validint : int     var input : string % user's input - can be anything     get input     % keep asking for input until it is a valid integer     loop         exit when strintok (input)         put "not a valid integer, try again"         get input     end loop     % send the valid integer to the main program     result strint (input) end validint % function to find a valid integer function validreal : real     var input : string % user's input - can be anything     get input     % keep asking for input until it is a valid real     loop         exit when strrealok (input)         put "not a valid real number, try again"         get input     end loop     % send the valid real number to the main program     result strreal (input) end validreal % Main program % Declare variables var num : int   % valid integer var num2 : real % valid real % Ask for input put "please enter an integer" num := validint put "please enter a real number" num2 := validreal

i didn't have a lot of time to make a really good error proofing program but this works. unless u enter ctrl z then it will crash but i don't really know how to error proof that

"% keep asking for input until it is a valid real"

to do this, u would need to use an if structure

you only need an if structure if you want a message popping up to the user... the code above works perfectly fine. The loop will exit the same way as a normal if structure

i know but im just giving another option
