SA0003: Empty statements

Function	Determines lines of code containing a semicolon (;) but no statement.
Reason	An empty statement can be an indication of missing code.
Exception	Although there are meaningful uses for empty statements. For example, it may be useful to explicitly program all cases in a CASE statement, including cases in which no action is required. If such an empty CASE statement is commented, the statistical code analysis does not generate an error message.
Importance	Low

Samples:

;                                // => SA0003
(* comment *);                   // => SA0003
nVar;                            // => SA0003

The following sample generates the error "SA0003: Empty statement" for State 2.

CASE nVar OF
    1: DoSomething();
    2: ;
    3: DoSomethingElse();
END_CASE

The following sample does not generate an SA0003 error.

CASE nVar OF
    1: DoSomething();
    2: ;                         // nothing to do
    3: DoSomethingElse();
END_CASE
