VAR topic

[nin]

I need help on this one my code is not working at all there is an error and i dont noe how to fix it 0.o..... the error is bolded and underlined.... the program needs to convert distance to miles or yards and it says on the paper "You may need to errortrap the input!"... and we cant use mod ...
_____________________________________________________________
%This program will convert a distance from miles to yards or yards to miles

%Declaration statement
var mOry : string
var yOrm : string
var distance : real
var answer : real
var number : real


%Program Title
locate (1, 34)
put "Converter"

%Program introduction
locate (3, 1)
put "This program allows you to convert distance to miles or yards."

%User Input and errortrap

locate (5, 1)
put "When you enter the type of measurement, please put either m or y."
put "m being miles and y being yards."
locate (7, 1)
put "Make sure that m or y is not capitalize."

locate (9, 1)
put "Please enter the type of measurement, m or y: " ..
get mOry
locate (10, 1)
put "Please enter the distance: " ..


%Processing
if mOry = "m" or mOry = "M" then
answer := number * 1760
mOry := "miles"
yOrm := "yards"
else
answer := number / 1760
mOry := "yards"
yOrm := "miles"
end if

if you havent noticed yet the error is

"Variable Has No Value"

This means one of the variables it is setting to has no value yet

(in your case NUMBER has not been set to anything)
you are missing your get number after asking for the distance

Hope This Helps

is this what you mean? ...

code:

var mOry : string var yOrm : string var distance : real locate (1, 34) put "Converter" locate (3, 1) put "This program allows you to convert distance to miles or yards." locate (5, 1) put "When you enter the type of measurement, please put either m or y." put "m being miles and y being yards." locate (7, 1) put "Make sure that m or y is not capitalize." locate (9, 1) put "Please enter the type of measurement, m or y: " .. get mOry locate (10, 1) put "Please enter the distance: " .. get distance if mOry = "m" or mOry = "M" then     put distance, " Miles Equals " ..     distance := distance * 1760     put distance, " Yards." else     put distance, " Yards Equals " ..     distance := distance / 1760     put distance, " Miles." end if

the error in your code is that u never got the distance and never put it to output either.

also...

code:

var answer : real var number : real

those two lines are kind of pointless
1) you dont even ever use them
2) u can reuse distance as u can see in what i did.

so i hope this is what u were needing help with/looking for.
