The empty Statement
An empty statement in Maple contains no command at all. For example, the empty statement is the second statement in:
The main purpose of the empty statement is to allow redundant semicolons to be used without causing a syntax error. For example, in strict Maple syntax there would be no semicolon statement separator following the cube statement below:
for i to 5 do
sqr[i] := i^2;
cube[i] := i^3
However, users who get used to ending all statements with a semicolon are accommodated since, if a semicolon follows i^3 here, then in the view of the Maple parser there is an empty statement prior to the keyword end do.
