TEXT:00,         is of course a variable. The equal sign means "is given the
COLOUR:POINTS
TEXT:00,variable
TEXT:16,           expression
COLOUR:STANDARD
TEXT:00,value of".            is either a constant value, another variable,
TEXT:16,or a complex formula. An expression is evaluated to a single value,
TEXT:16,which is then stored in the variable to the left of the equal sign.
TEXT:32,Let's begin with a simple example of assigning a variable with a value:
COLOUR:EUPHORIA
TEXT:32,atom year, copy_of_year
TEXT:16,year = 1997
TEXT:16,copy_of_year = year
COLOUR:STANDARD
TEXT:32,(Author's note: first, you could say the above is a simple example
TEXT:16,of a program, and second, from this time forth, any examples involving
TEXT:16,Euphoria will always show the appropriate variables declared.)
