Spaces and Tabs
Every part of a statement that consists of more than one word has to be separated by a space:
CREATE LINE
APPEND LINE SEGMENT
CREATE CALLOUT
Multiple spaces have no effect on the macro. You can take advantage of this flexible formatting to make your code more readable (by lining up assignments, indenting, etc.):
CREATE LINE 125 678 254 223
CREATE LINE 658.225 568.554 874.974 336.889
