Another early programming language was devised by Grace Hopper in the US, called FLOW-MATIC. It was developed for the UNIVAC I at Remington Rand during the interval from 1955 till 1959. The FLOW-MATIC compiler became publicly out there in early 1958 and was considerably full in 1959. FLOW-MATIC was a major influence within the design of COBOL, since only it and its direct descendant AIMACO were in actual use on the time. It was the first widely used high-stage basic purpose programming language to have a useful implementation, as opposed to only a design on paper.
- Once data has been specified, the machine should be instructed to perform operations on the info.
- A language is typed if the specification of each operation defines types of knowledge to which the operation is relevant.
- For example, the information represented by “this text between the quotes” is a string, and in lots of programming languages dividing a number by a string has no that means and will not be executed.
- Many languages allow a operate known as an exception handler to deal with this exception and, for example, at all times return “-1” as the end result.
