Both examples provide identical functionality, but the use of indentation, either
spaces or tabs to show the construction of the statements aids readability.
The use of the ELSEIF statement in this example was omitted for clarity.
Typical Examples
count = 75
result = log(count)
count = 75 : result = log(count)
Both examples provide identical functionality, but the use of the colon between
statements allows both to reside on the same line.
Typical Examples
result = 20 + 30 * 40
The result is 1220.
result = (20 + 30) * 40
The values in parenthesis are calculated first. The result is 2000.
