The EiffelBase class library, covered by the open-source IFFEL license, is one of the principal contributions of Eiffel: a library of fundamental structures and algorithms covering the basics of computing, and resulting from a "Linnaean" effort at a general-purpose taxonomy of computing structures. EiffelBase is one of the most carefully designed and extensively used libraries in the object-oriented industry.

Because the Pick-and-Drop operation has been so popular, classes have been added to the EiffelVision 2 library to make implementing this user interface very easy.

Because <eiffel>print</eiffel> takes an argument of type [[ref:libraries/base/reference/string_8_chart|STRING_8]], button2 becomes a valid drop-target for the pebble contained by button1. Right clicking the mouse pointer over the '''source''' will start the transport, and right clicking with the mouse pointer over a valid '''target''' will complete the transport. The transport can be canceled anytime with a simple left click, just as you would do in EiffelStudio.
{{note|Any type of object can be used as the '''pebble'''.
