This article is about 4GL software. For other meanings, see Mark IV (disambiguation).

MARK IV is a Fourth-generation programming language that was created by Informatics, Inc. (later, Sterling Software) in the 1960s. Informatics, Inc. took advantage of IBM's decision to unbundle their software; MARK IV was the first "software product to have cumulative sales of $10 million".

MARK IV was developed for IBM Systems (360 and 370) and for the RCA Spectra 70. Its main benefit was allowing faster application development on the order of 6 to 10 times faster than doing a system using a 3GL, such as COBOL. MARK IV , being an early 4GL, allowed user development of systems related to business. In an 1971 ad by Informatics, there are several quotes from customers, such as:

We conservatively estimate that the benefits derived from the MARK IV System have completely returned the cost of our investment in a period of less than 3 months.
MARK IV runs ... handle Accounts Receivable, Inventory, Sales Analyses, etc. on about 26 different factories..

MARK IV (as VISION:BUILDER) is now part of the product suite from Computer Associates.
