B.1 Comments
B-2
Declare constants
Declare public variables,
dimension array, and declare
units.
Define data table
Measure
Call data table
Comments are nonexecutable text in the body of a program. Comments
document or clarify the program. As shown in CRBasic Example B-2, insert
comments into a program by preceding the comment with a single quote (').
Comments can be entered either as independent lines or following CR300
