who develops the first computer language called cobol CODASYL what is the acronym of the computer language? common business-oriented language who developed it? CODASYL what does the picture clause do? A clause is a string of characters, each of which represents a portion of the data item and what it may contain. For example, a indicates a decimal digit, and an indicates that the item is signed. does it have any influence on other programming languages? Yes -  Its record and file structure influenced PL/I and Pascal what is the history of the first mentioned language? IBM wanted a single programming language for all users. It hoped that Fortran could be extended to include the features needed by commercial programmers. In October 1963 a committee was formed  to propose these extensions to Fortran. They designed a new programming language based loosely on ALGOL labeled MPPL  and, in 1965, with PL/I

PL/I [SEP] Introduction
PL/I (Programming Language One, pronounced and sometimes written PL/1) is a procedural, imperative computer programming language developed and published by IBM. It is designed for scientific, engineering, business and system programming. It has been used by academic, commercial and industrial organizations since it was introduced in the 1960s, and is still used. PL/I's main domains are data processing, numerical computation, scientific computing, and system programming. It supports recursion, structured programming, linked data structure handling, fixed-point, floating-point, complex, character string handling, and bit string handling. The language syntax is English-like and suited for describing complex data formats with a wide set of functions available to verify and manipulate them.
