CIGAL recognizes hundreds of different words as either data variables or commands. Some variables and commands are internally defined, others are user-defined.

The program looks for the meaning of each word entered in a command line by a 4-step process checking:

      1) the list of DEFINE'd names
      2) the list of internally declared variables
      3) the list of user-declared variables
      4) the list of internally defined commands and functions.

In the first 3 of these steps only exact matches are accepted, but CIGAL will recognize any unambiguous abbreviations (of 2 or more letters) for command or function names.

The following is a list of CIGAL's internally defined words organized by command or variable type. The names in this list should normally be treated as reserved words and therefore should not be used as names for variables or macro programs. (It is possible, however, to change the meaning of any reserved word by using the DEFINE command.) These names are listed in alphabetical order.
