if statements help

[cycro1234]

Aight, so i'm learning this new thing in turing called "error trapping". Annoying lil bugger if u ask me, but important nonetheless. Neways, lets say I have an if statement for one value. And i want the program to end when the value is something other than the one i want. That is, ANY value, meaning string or real number. Example:

get x

if x = 5 then
put "<Insert witty comment here>"

now i need the code to make the program output the next part IF x is any value other than 5, including strings.

put "You will read this if you inputted any other value for x other than 5" put "including a string"

else would work, but only if the input is a real type. I need to cover ALL possiblities. Thx in advance

Your question is kinda convoluted and hard to understand. But I'll post an example error trapping statement and you can probably adapt it to your own use. Say you want the user to input an INTEGER. This is what you do:

code:

var userInput : string loop     put "Please enter an integer:  " ..     get userInput     if strintok (userInput) then         put "Congratulations! You know what an integer is!"     else         put "You suck. That's not an int!"     end if end loop

ok but what if i dont want to do it for an integer? What if i want to do it for a string?

Nvm, i think i got it. THX A LOT!

UGH! I didn't get it. I want the user to input a real number. If the user inputs a letter instead of a number, i want the program to tell the user to input again properly.

I'm not that good with string manipulation but here's my approach:

code:

var userInput : string loop     locate (1, 1)     put "Enter a real number : " ..     get userInput     exit when index ("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghigjklmnopqrstuvwxyz,<>/?;':\"[]{}`~!@#$^&*()_+|-", userInput) = 0     locate (1, 1)     put repeat (" ", maxcol) end loop var realNum := userInput put "You entered ", realNum, "."

code:

var input : string var num : real loop     put "Enter a real number: " ..     get input     cls     exit when strrealok (input)     put "That was not a real number!" end loop num := strreal (input) put "The number entered is ", num

ah hell I didn't think there was a strrealok command. I must have typed strealok when I first tried it.
Given that there is a strrealok command, use beard0's code 8)

uh oh

[con.focus]

shoot sry if u want it to end when it encounters sumthing else then use a loop and tell use the exit when command to tell it when to stop the loop

[beard0]

con.focus: what does that code have to do with asking for numerical input, and allowing user stupidity (ie, they enter a non-number)?
