Hi everybody,
I am an absolute beginner - so far. What I did not find out in studying the manual: How can I INPUT numeric data and how can I PRINT numeric data. The INPUT/PRINT statements so far seem to be only for string data. E.g. I want to:
INPUT number1
INPUT number2
x = number1 + number2
PRINT x
How does this work with purebasic?
Thank you,
Roland

Code: Select all
number1 = Val(InputRequester("First Number", "Please make your input:", "")) ;INPUT number1
number2 = Val(InputRequester("Second Number", "Please make your input:", "")) ;INPUT number2
x = number1 + number2
MessageRequester("Sum",Str(x)) ;PRINT x
Here is one method to accomplish what you require using Requesters, one for input one for output. They deal only with strings, so numbers have to be converted both ways.
Another method involves console output (a text only screen). This method is the one you referred to with Input and Print. Use a method similar to the one I demonstrated to do the conversions betwen numbers and text.
Another method involves a GUI (graphic user interface) using gadgets for input and displaying the results.
I hope this helps.

Code: Select all
OpenConsole()
Num1.s = Input()
Num2.s = Input()
x.l = Val(Num1) + Val(Num2)
PrintN(Str(x))
Input() ; give you a chance to see the output before the console screen vanishes
CloseConsole()

Rolstra,
If you are a complete beginner as you say, I would recommend for you to have a look at a site which has been put up by 1 of the forum users here ( blueznl ) which I think will probably help you a lot.
