Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:
Error("An error was detected while entering the address." + CR + ...
"Modify the personal details of the customer.")
is equivalent to:
Error("An error was detected while entering the address. ", ...
"Modify the personal details of the customer.")

Displaying the last error message

Error used with no parameter (syntax 2) displays the error message corresponding to the last WLanguage function that triggered an error.
In this case, the following code:
Error()
is equivalent to:
Error(ErrorInfo())
Caution: Error must be used immediately after the call to the function that failed. Indeed, the call to a WLanguage function can reinitialize and modify the error report returned by Error.
