PerForm and PerForm PRO were electronic form programs, initially designed to work under GEM in DOS. Later versions were designed to work in Windows 3.1, at which point it was succeeded by FormFlow.
The initial version of PerForm was created in 1988 and was the first product released by Canadian software firm Delrina, which became best known for its later fax software program, WinFax.
The electronic forms division of Delrina was sold to JetForm in 1996. JetForm in turn was bought by Adobe, and the electronic forms products were officially discontinued in 2004.
