The -modernsyntax compiler option disables some legacy language features
These features are
•&& for single line comments
? Today() && Show today's date
•* for whole line comments
* The next line calls DoSomething()
? DoSomething()
•Bracketed strings
? ["''"] // use brackets to include quotes in a literal string
•Parenthesized expression lists
var x := IIF(Dow() == 1, (Open(), DoSomeWork(), Close()), 42)
These were used by some users to include more than one expression / function call on locations where a single expression was expected, such as inside an IIF() expression. If -modernsyntax is not enabled then the compiler will generate a local function with (in this example) 3 expression statements and insert a call to the local function in the IIF() expression.
To set this compiler option in the Visual Studio development environment:
1.Open the project's Properties page.
2.Click the Language tab.
3.Change "Modern Syntax" value of checkbox
