JavaScript, JScript

function ReadLineByLetters()
{
  var sPath = "D:\\Files\\MyFile.txt";

   // Opens the specified file for reading
  var myFile = aqFile.OpenTextFile(sPath, aqFile.faRead, aqFile.ctANSI);

  // Obtains the length of the first line
  var lLeng = myFile.LineLength(0);

  // Posts the first line by letters to the test log
  for (var i = 0; i < lLeng; i++)
    Log.Message(myFile.ReadString(1));

  // Closes the file
  myFile.Close();
}

Python

def ReadLineByLetters():
  sPath = "D:\\Files\\MyFile.txt"
  # Opens the specified file for reading 
  myFile = aqFile.OpenTextFile(sPath, aqFile.faRead, aqFile.ctANSI)
  # Obtains the length of the first line
  lLeng = myFile.LineLength(0)
  # Posts the first line by letters to the test log
  for i in range(0, lLeng):
    Log.Message(myFile.ReadString(i))
  # Closes the file 
  myFile.Close()

VBScript

Sub ReadLineByLetters
  sPath = "D:\Files\MyFile.txt"

   ' Opens the specified file for reading
  Set myFile = aqFile.OpenTextFile(sPath, aqFile.faRead, aqFile.ctANSI)

  ' Obtains the length of the first line
  lLeng = myFile.LineLength(0)

  ' Posts the first line by letters to the test log
  For i = 0 to lLeng-1
    Log.Message(myFile.ReadString(1))
  Next

  ' Closes the file
  myFile.Close()
End Sub

DelphiScript

function ReadLineByLetters;
var sPath, myFile, lLeng, i;
begin
  sPath := 'D:\Files\MyFile.txt';

   // Opens the specified file for reading
  myFile := aqFile.OpenTextFile(sPath, aqFile.faRead, aqFile.ctANSI);

  // Obtains the length of the first line
  lLeng := myFile.LineLength(0);

  // Posts the first line by letters to the test log
  for i := 0 to lLeng-1 do
    Log.Message(myFile.ReadString(1));

  // Closes the file
  myFile.Close();
end;

C++Script, C#Script

function ReadLineByLetters()
{
  var sPath = "D:\\Files\\MyFile.txt";

   // Opens the specified file for reading
  var myFile = aqFile["OpenTextFile"]( sPath, aqFile["faRead"], aqFile["ctANSI"] );

  // Obtains the length of the first line
  var lLeng = myFile["LineLength"](0);

  // Posts the first line by letters to the test log
  for (var i = 0; i < lLeng; i++)
    Log["Message"]( myFile["ReadString"](1) );

  // Closes the file
  myFile["Close"]();
