JJ Words Web Page

Welcome to the JJ words page. This page introduces you the words used in JJ. These words are part of JJ, and thus cannot be used as NAMEs in your JJ code. For example, the word 'If' is a JJ word, it is used to start an If command. Thus, you cannot use the word If as a NAME: 
   Box if ofType int           -- CheckIt error
   Start
   Outputln "Enter a number:"
   Input if				 -- this command will also have to change

Command words start with a capital, but so do some other words.
If you look at the JJ Command page, you will see that every word which starts a JJ command starts with a capital letter. There are other words, however, that also start with a capital letter. For example, the word 'Str' is the name of a JJ class, and since class names start with capital letters, so does the word 'Str'. Another example is the word 'Cos'. Built in math function, like Cos, Sin and Tan all start with a capital letter.

Words For Commands

Some commands do not have any special JJ words besides the first word. For example, a Class command starts with the JJ word 'Class', but does not contain any other JJ words. (The Class command is the word 'Class' followed by a NAME for the class). Here is a list of words that may be used with each command:
