Function Error(message, caption, url, urlText)

Reports an evaluation-time error, displaying the indicated «message» to the end user in a dialog box and ending the current computation.

If the expression in a Check Attribute calls Error(), it displays the error message as a warning dialog, instead of the default failed-check message that otherwise appears when the Check Attribute evaluates to False (0).

The optional «caption» parameter controls the text that appears on the title bar of the error dialog.

The optional «url» and «urlText» can be specified if you want to include a hyperlink on the error's message box.

Examples

If not IsNumber(x) Then Error("Something is wrong. x is not numeric.");

Error( "The matrix to MapKernel must be positive definite",
url: "https://mywebsite.com/Details/Using_MapKernel.html",
urlText:"Info on this error")
