The PERQ was a popular early graphical workstation; therefore, it helped spawn many early third-party applications that took advantage of the [[graphical user interface]] and [[raster graphics|bitmapped graphics]]. [[Intran]] (around 1982) produced a pioneering graphical program suite called MetaForm, which consisted of the separate Graphics Builder, Font Builder, Form Builder, and File Manager programs. The PERQ also served as a dedicated platform for several pioneering [[hypertext]] programs, such as [[ZOG (hypertext)|ZOG]], [[KMS (hypertext)|KMS]], and [[Guide (hypertext)|Guide]]. DP ("Drawing Program"), a [[Computer-aided design|CAD]] system used for creating [[circuit diagram]]s on the PERQ, was written by Dario Giuse at CMU.<ref>{{Cite web |url=http://oai.dtic.mil/oai/oai?&verb=getRecord&metadataPrefix=html&identifier=ADA126401 |title=Entry for ''DP - Command Set'' at the  Defense Technical Information Center |access-date=2008-12-03 |archive-url=https://web.archive.org/web/20090531004614/http://oai.dtic.mil/oai/oai?&verb=getRecord&metadataPrefix=html&identifier=ADA126401 |archive-date=2009-05-31 |url-status=dead }}</ref>
