Conventions

You will also find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text are shown as follows: "The contents of the display field are stored in the currentValue variable and the last operator button you pressed (that is stored in currentCommand) is looked at, to see what happens next."

A block of code is set as follows:

on togglesign
  if character 1 of field "display" is "-" then
    delete character 1 of field "display"
  else
    put "-" before field "display"
  end if
end togglesign

Any command-line input or output is written as follows:

start using stack "utility stack"

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In the Tools palette, click on the Edit tool (the top-right icon)."

Note

Warnings or important notes appear in a box like this.
