understanding Pascal
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.
