Editing Anders Hejlsberg (section)

== Early life ==
Hejlsberg was born in [[Copenhagen]], [[Denmark]],<ref>{{Cite web|title=Anders Hejlsberg|url=https://www.computerhope.com/people/anders_hejlsberg.htm|access-date=2021-12-06|website=www.computerhope.com}}</ref> and studied Electrical Engineering at the [[Technical University of Denmark]]. While at the university in 1980, he began writing programs for the [[Nascom]] [[microcomputer]], including a [[Pascal (programming language)|Pascal]] compiler which was initially marketed as the ''Blue Label Software Pascal'' for the [[Nascom-2]]. However, he soon rewrote it for [[CP/M]] and [[DOS]], marketing it first as ''Compas Pascal'' and later as ''PolyPascal''. Later the product was licensed to [[Borland]], and integrated into an [[Integrated development environment|IDE]] to become the [[Turbo Pascal]] system. Turbo Pascal competed with PolyPascal. The compiler itself was largely inspired by the "Tiny Pascal" compiler in [[Niklaus Wirth]]'s "''[[Algorithms + Data Structures = Programs]]''", one of the most influential computer science books of the time.<ref name="ACM"/>
