Think about how x-coordinates change base on length of the string you are writing in the font you are writing in.

sure thing.

If you are using plain text, you'll need
length() - length of string
locate() - moving the cursor before the put statement

If you are using graphics text, you'll need
Font.Draw() - obviously to draw the text itself
Font.Width() - to calculate the width of the text string

We aren't suppose to write code for you. But we can give you advice. Why don't you attempt the problem first?

think about the length of the text between "Hello world" and "baz bar foo baz bar foo"

Also,
If you are using plain text, you'll need
maxcol - columns in the "console"
maxrow - rows in the "console"

If you are using graphics text, you'll need
maxx - width of the window
maxy - height of the window

-----------------------------------

This is what I got so far


procedure centerText
Font.Draw (centerText , maxx div 2, maxy div 4, font, black)
end centerText

cls
centerText ("Loading Please Wait...")
centerText ("Press Anykey to continue")
Input.Pause


it says assignment wrong type :S

take a closer look at what you're doing. You're drawing a procedure and that wont work, hence error. What you want to do is find the width of the string using Font.Width(), divide it by 2 and subtract that amount from the x coord. You will probobly want to also structure your procedure like so:


procedure centerText (text :string, x, y :int)
   %draw the text here
end centerText


you would then call the procedure like this:

centerText ("Centered text :)", 200, 200)


this will draw "Centered text :)" at 200 over and 200 up (x, y)
