By convention, global variables in the standard macro package use capital letters orbegin with an underscore. Variables can be made constant to protect them fromaccidental reassignment,12.FOURC> constant Lambda 1.5413.FOURC> Lambda = 1.7Trying to assign to a constant ‘Lambda’.14.FOURC>Variables defined as constant are automatically global.Most built-in variables with preassigned values are of the immutable type and cannotbe changed at all:14.FOURC> PI = 1Trying to assign to an immutable ‘PI’.15.FOURC>Some built-in variables, such as DEBUG ,can be changed by the user. Another variable,the A[] array, may be filled by the program with the current motor positions orcan be set to target motor positions.
