PASCAL - TUTORIAL FILE TEXT

Hi programmer.. You are on my site in “We Are Knowledge”. In here you will getting many IT knowledge. IT knowledge based web programming likely html and php, based dekstop programming likely pascal, cobol, c++ and other program language… in here the programmer can looking for IT knowledge.

This is the right blog for begginer programmer..  because I was making tutorial from from the base to a higher level. Example if you will programmer you must learn dekstop programming and next web programming.

But now, I want giving you IT knowledge based dekstop programming. That is “program language PASCAL” and discuss about FILE in Pascal. You want to know? Let’s do read my article.. have fun for reading…

FILE

>> Files in pascal is a collection of byte-byte stored in the storage media (in pascal program). A component (an element of the file) the same data type, which is not necessarily the amount that can be reduced or increased if anyone wants to change.

Pascal files on there are some we need to know, and there are 3 types of files, namely:

1. Text file

2. files of type

3. File not type

Ok… now.. I want explain to you one by one. But I want giving you knowledge just “TEXT FILE”

1. Text file

Creating text file with pascal :

a.  Declaring a variable syntax for file

var name_variable : TEXT;

b.Linking syntax for file names with variable file

assign (name_variable, name_file);

c.  Creating a text file to be active (in use)

rewrite (name_variable);

d. Writing into a text file (edit file)

write / writeln (name_variable, value data 1, value data 2, valu data 3, and so on)

e.  closing the file

close (name_variable)

Reading Text Files with pascal

a.  Declaring a variable syntax for file

var name_variable : TEXT;

b.Linking syntax for file names with variable file

assign (name_variable, name_file);

c. Reading pascal file contents and display it in the windows or on the output window

while not eof (name_variable)

begin

readln (name_variable, value data 1, value data 2, valu data 3, and so on);

write (value data 1, value data 2, value data 3, and so on);

end;

d.  closing the file

close (name_variable)

Add the contents of the file created by pascal

assign

>> Linking syntax for file names with variable file

Append

>> additions to pre-existing file contents

Ok.. just it

I hope you likely..

See you later..
