Conventions used

There are a number of text conventions used throughout this book.

CodeInText indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. An example of this is as follows: "The HelloWorld.al file can be deleted immediately."

A block of code is set as follows:

IF Type = 'Resource' THEN No. := Resource.No. 
  ELSE IF Type = 'Show' THEN No. := Radio Show.No. 
    ELSE IF Type = 'Item' THEN No. := Item.No. )

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold, as follows:

IF Type = 'Resource' THEN No. := Resource.No. 
  ELSE IF Type = 'Show' THEN No. := Radio Show.No. 
    ELSE IF Type = 'Item' THEN No. := Item.No. )

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

$ cd css

Bold indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this, such as "From Visual Studio Code, click on New, then click on File."

Warnings or important notes appear like this.

Tips and tricks appear like this.
