Pascal is a high-level language (High Level Language) programming language that is easily understood by human language. Pascal is a structured language consisting of a number blok.Blok small-block that can then be used to create larger blocks. This block is better known as subprograms, which are distinguished on the procedures and functions. Pascal was first made ​​by Professor Niklaus Wirth, a member of the International Federation of Information Processing (IFIP) in 1971.

The advantages of Pascal programming language are:
Standard Data-Type, standard data types are already available in most programming languages​​. Pascal has a standard data types: boolean, integer, real, char, string,
User-defined Data Types, programmers can create other data types derived from standard data types.
-Strongly-typed, the programmer must specify the data type of a variable, and variables can not be used to store data types other than the specified format.
-Structured, has a syntax that allows the writing of the program is broken down into smaller functions (procedures and functions) that can be used repeatedly.
-Simple and Expressive, has a simple structure and very close to human language (English) so it is easy to learn and understand.

Disadvantages pascal language:

-An early version of Pascal's less suitable for business applications because of the limited database support.

-Pascal syntax is too long-winded
-Does not support object-oriented programming
-Pascal is not flexible and required a lot of flaws to make large applications.
