 Of course you can use both at the same time:
-<code visualfoxpro>cString := ei"this is a \"string\". that references {cLocalVar}"</code>
+<code visualfoxpro>cString := ei"this is a \"string\". that references {cVariableName}"</code>
 As variable, not only a string variable can be used, but every type of object, and under the houd the '':ToString()'' method is called:
@@ Line 29: / Line 29: @@
 cString := i"This is {oPerson}"</code>
+And if you wish, you can also use formatting expressions:
+<code visualfoxpro>local nValue		as decimal
+nValue			:= 123.45m
+cString := i"nValue: {nValue:######.0000}" // nValue: 123,4500
+cString := i"nValue: {nValue:F6}" // nValue: 123,450000</code>
+In this case (as in the use with ToString()), if you need to embed the parentheses ''{'' and ''}'' in your string, they need to be doubled as in this sample:
+<code visualfoxpro>cConnection := i"Driver={{Microsoft access Driver (*.mdb)}};Dbq={cDatabaseFile};Uid=Admin;Pwd=;"</code>
 And only in the VO dialect, you need to prefix a char with the ''c'' prefix:
 <code visualfoxpro>cChar := c'a'</code>
+Please note that there is a major difference between C# and X#: in C# all strings are enhanced, and to make them normal, you must prefix them with the ''@'' character.
+In X# all strings are normal, and to be enhanced, they need the ''e'' prefix.
