The empty Statement

Description

• 

SYNTAX: null;

• 

An empty statement in Maple contains no command at all. For example, the empty statement is the second statement in:

a:=1; ;quit

• 

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

end do;

• 

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.
