AssignFile

The AssignFile procedure assigns a value for a FileName in preparation for reading or writing to that file.

Version 1

Takes a text file variable type as the handle. The file is treated as a textfile when opened. If the file name is an empty string, then file access is made to the console standard input and output streams.

Version 2

Takes a binary file variable type as the handle. The file is treated as a binary file.

In both cases, when the file is opened by Append, Reset or ReWrite, it is assumed to be in the current directory.

Example:

TRObject Syntax

 var
   myFile : TextFile;
 
 {
   // Try to open the Test.txt file for writing to
   AssignFile(myFile, Clomosy.AppFilesPath+'TaskList.txt');
   ReWrite(myFile);
   
   ShowMessage('The file is added to the directory where the exe is located.'); 
   
   // Write a couple of well known words to this file
   WriteLn(myFile, 'Task 1');
   WriteLn(myFile, 'Task 2');
   ShowMessage('Lines have been added to the file.'); 
   // Close the file
   CloseFile(myFile);
 }

Base Syntax

 var
   myFile : TextFile;
 
 begin
   // Try to open the Test.txt file for writing to
   AssignFile(myFile, Clomosy.AppFilesPath+'TaskList.txt');
   ReWrite(myFile);
   
   ShowMessage('The file is added to the directory where the exe is located.'); 
   
   // Write a couple of well known words to this file
   WriteLn(myFile, 'Task 1');
   WriteLn(myFile, 'Task 2');
   ShowMessage('Lines have been added to the file.'); 
   // Close the file
   CloseFile(myFile);
 end;

Output:
After the file has been saved, it appears as follows.
