Line 138:

* [[Ada_language|Ada]] inspired some of large-scale program support, exception handling, tasking, and supportability aspects.

* [[Basic programming language|Basic]], notably in the more modern variants that dispense of line numbers and support structured programming, showed how simple the syntax of a programming language could be. For instance, Basic remains one of the only modern languages to not mandate parentheses around subroutine calls.

* [[C_language|C]] was used as the standard to expect in terms of runtime and machine-level support. XL will not require a virtual machine to run.

* [[C++]] and the [[Standard template library]] demonstrated the need for good support of generic types, including implicit instantiation of generics (which Ada lacks).

Line 146:

* [[Prolog]] demonstrated that alternative programming models are sometimes useful and highly productive. Every effort was made to ensure that a Prolog-style plug-in could be written for XL.

* [[Visual Basic]] showed how the parse tree representation can be dissociated from its visual presentation. Few people edit VB Forms textually. It is expected that XL edit-time plug-ins will one day provide similar capabilities, by directly manipulating the parse tree.
