What are the shortcomings of procedure oriented approach?

Programming in FORTRAN, COBOL and C are known as procedure oriented programming (POP) language.The problem with these language is that, in this approach things are done in a sequential manner.  

The drawbacks of procedure oriented programming (POP) language are as follows:

1. Procedure oriented programming language does not model real world problems efficiently.

2. Procedure oriented programming language, we groups number of instructions which further are executed by the compiler in a serial manner.

3. In procedure oriented programming language, global data are more prone to undesirable changes which can be accidentally made by a function call.

4. In Procedure oriented programming, data moves openly around the system from one function to another. Functions can transform data into different forms.

5. Procedure oriented programming language contains many functions important data items and are made global so that they are easily accessible by all the functions.
