Language H
Language H is a proprietary, procedural programming language created by NCR based on COBOL. The first compiler was developed in August 1962 to run on the National-Elliott 405M and produce object code for the National-Elliott 803B.[1] It is believed that the "H" stands for John C Harwell.[2]
