Examining the program will reveal two loops, one nested within the other, and both ranging in value from 1 to 8. To use either of the two variables in a program, we must add two subscripts to the variable name to tell the program which element of the 64 we desire to use. Another way to achieve the same end is to define the double array as in the next line of the program where Value is defined as a total of 64 elements. This is called a doubly subscripted array and it can be envisioned in exactly the same manner as a real checker board, an 8 by 8 matrix. The variable Checkerboard is actually composed of 8 elements, each of which is 8 elements, leading to a total of 64 elements, each of which is a simple integer variable. You will see that Checkerboard is defined as an array from 1 to 8, but instead of it being a simple data type, it is itself another array from 1 to 8 of type integer. Compile and run this program.ДЄfter understanding the above example program, load the program to see the next level of complexity of arrays. Keep in mind that the array is actually composed of 12 different integer type variables that can be used in any way that it is legal to use any other integer type variable. Review this material and this program as long as needed to fully understand it, as it is very important. Note carefully that, although the subscripts are limited to 1 through 12, the values stored in each of the 12 variables are limited only by the range of integers, namely -32768 to 32767. With known values stored in the array, a header is now printed and the list of values contained in the array is printed. Any integer values could be used, this was only a convenient way to set the values to some well defined numbers.

As Index is varied from 1 to 12, the range of the subscripts of the variable Automobile, the 12 variables are set to the series of values 11 to 22. The subscript moreover, must be of the type used in the definition and it must be within the range defined or it will be construed as an error. Each time one of the variables is used, it must have the subscript since the subscript is now part of the variable name. In using the elements of the array in a program, each of the elements of the array are required to be used in exactly the same manner as any simple variable having the same type. The array definition given in line 5 is the standard definition for an array, namely a variable name, followed by a colon and the reserved word array, with the range of the array given in square brackets followed by another reserved word of and finally the type of variable for each element of the array. The square braces are used in Pascal to denote a subscript for an array variable. The variable Automobiles is defined as an integer variable but in addition, it is defined to have twelve different integer variables, namely Automobile, Automobile, Automobile. Display the Pascal program ARRAYS.PAS and notice line 5 starting with the word Automobiles. Let's go directly to an example to see what an array looks like. One of the most useful Pascal data structures is the array, which is, in the simplest terms, a group of 2 or more identical terms, all having the same type. Having covered nearly all of the programming statements, we must now go back and fill in some gaps in our data definition and look at the array in particular. But standard Pascal doesnвЂ™t use recursion in its programs.At the beginning of this tutorial we said that a computer program is composed of data and executable statements to operate on that data. It is also used to pass the recursive calls to others.

Turbo Pascal uses local variables that are handled in the recursion phase.

Read and Write procedures help in extending the functionality of the I/O methods.

Turbo Pascal uses Read and Write procedures in place of Get and Put methods.

Turbo pascal is used it to show the standard procedures like new, mark and release.

Turbo Pascal uses the dynamic variables and pointers whereas Standard Pascal doesnвЂ™t use it.

Turbo Pascal is more efficient, faster and doesnвЂ™t require any support code for compatibility factor whereas Standard Pascal doesnвЂ™t, acknowledge the record descriptions for the standard methodology.The difference between Turbo Pascal and Standard Pascal is given below:

It is the first software development system which has editor, linker and compiler all in one application. Developed by Borland, it runs on a variety of Operating systems such as CP/M, PC-DOS, and MS-DOS. It is developed for the Pascal Programming. Turbo Pascal is a comprehensive software development system released in the year 1983.
