-@noindent One can select an element, or some elements, in a @dates object as he would extract some elements from a vector in Matlab/Octave. Let @code{a = 1950Q1:1951Q1} be a @dates object, then @code{a(1)==1950Q1} returns @code{1}, @code{a(end)==1951Q1} returns @code{1} and @code{a(end-1:end)} selects the two last elements of @code{a} (by instantiating the @dates object @code{[1950Q4, 1951Q1]}).

+@noindent Dynare substitues any occurence of dates in the mod file into an instantiation of the @dates class regardless of the context. For instance, @code{d = 1950Q1;} will be translated as @code{a = dates('1950Q1');}. This automatic substitution can lead to a crash if a date is defined in a string. Typically, if the user wants to display a date:
+
+@example
+disp('Initial period is 1950Q1');
+@end example
+
+@noindent Dynare will translate this as:
+
+@example
+disp('Initial period is dates('1950Q1')');
+@end example
+
+@noindent which will lead to a crash because this expression is illegal in Matlab. For this situation, Dynare provides the @code{$} escape parameter. The following expression:
+
+@example
+disp('Initial period is $1950Q1');
+@end example
+
+@noindent will be translated as:
+
+@example
+disp('Initial period is 1950Q1');
+@end example
