Conditional Statements and Version Numbers

[Scott Kane]

G'day,

In some other programming languages it's possible to use conditional defines 
to conditionally run parts of your code.  This is particuarly useful when 
done in combination with version or build numbers.  I can't seem to find 
similar methods in Rev.  That is to say I can't find conditional defines or 
the ability to get a stand alones version or build number (though I can 
certainly find out the version or build of the Rev engine used to built it).

For example

{$ ifDef myDefine}
Do some code
{$End If}

The $ being a compiler directive.  Is either of these possible in Rev?
