Here is some more information.
I have a form which includes two buttons. The first one is for reading in the file, (which has only one line of text). Here is my coding.

PUBLIC SUB Button1_Click()

  DIM lineIn AS String
  DIM fileIn AS File
  DIM fname AS String
  fname = "/home/neilwin/basic/trial.txt"
  
  OPEN fname FOR READ AS #fileIn
  LINE INPUT #fileIn, lineIn
  result.Text = ""  
  result.text = result.text & lineIn
  FLUSH #fileIn
  CLOSE #fileIn

END

There is also a text box which I have renamed result.  I make a few changes to the line of text and then I click on another button to write the changed file back to the hard disk. Here is the code

PUBLIC SUB Button3_Click()

  DIM fileIn AS File
  DIM fname AS String
  fname = "/home/neilwin/basic/trial.txt"
  OPEN fname FOR CREATE AS #fileIn
   WRITE #fileIn, result.Text
   CLOSE #fileIn

END

Perhaps I should add that I am new to Gambas but not new to computers.

When I check the new version of the file in Konqueror  the changes are there but there is one extra character at the very start of the line. 

Is there a better way to do what I want?  Thanks for any help,

Neil
