PROIV (pronounced "pro-four"), also known as 'Pro-IV',^[1] is a low code development platform owned by Zellis Holdings,^[2] a British HR services company.^[3]

PROIV was originally developed as a fourth-generation programming language (4GLs). PROIV and other 4GL are aiming to simplify and reduce efforts to create and develop computer programs compared to third-generation programming languages (3GLs) such as Cobol and Fortran.^[4]

PROIV's usual application domain is database-centric business applications.^{[citation needed]}

PROIV programs consist of declarative/non-procedural specifications that control the overall structure of the program and database access and that have an implicit sequence of execution (which PROIV programmers refer to as the timing cycle). Procedural subroutines can be added by the programmer; these are written in a 3GL-like language, which PROIV calls "Logic".
