Figure 12.28 is shown in Figure 12.29.
Some commonly known fourth-generation languages are ADR's Ideal, Software

Points to Remember
A language that is acceptable to a computer system is called a computer
language or programming language, and the process of writing instructions in such
a language for an already planned program is called programming or coding.
All computer languages can be broadly classified into three categories,
