Solutions: Fourth Generation Language (4GL): A 4GL, Fourth Generation Language, refers to the most recent level of programming languages whereby programs are written that consist of commands from the application package which is written in a second or third generation language. Although the terms 1GL, 2GL, and 3GL are rarely used, 1GL refers to machine language programming, the lowest level computer language. 2GL refers to assembly language programming, and 3GL then refers to all the third generation programming languages such as BASIC, COBOL, FORTRAN, PASCAL, C, Ada, etc. where the source code is compiled to create an executable program file or application package. Query languages and report writers are fourth-generation languages. A dBASE program is a good example of a 4GL program. |
