procedure Assert (Condition: Boolean);or
procedure Assert (Condition: Boolean; const Message: String);
Assert
checks the given Condition
at run-time. If it
is true, it does nothing. If it is false, it raises a runtime error,
using the second argument for the message if given.
However, if the switch --no-assertions
is given
(see GPC Command Line Options), Assert
is deactivated. It
still evaluates the condition if it has side effects, but never
raises a runtime error.
Assert
is a Borland Delphi extension.
