Statements
Within a function SIMPOL is made up of statements. Typically a statement will occupy a single line within the source code, but more
than one statement can be placed on one line by separating them with semi-colons (;) or colons (:).
Also it is possible to break a statement into more than one line; the backslash (\) character is used to indicate that
the following line is a continuation of the current one, but is only valid if it is the last non-white-space character on the line.
