A .doc or .docx file is not a text file; it contains all sorts of binary data. I created example.docx containing just the text "Hello, world.". It came out as nearly 4 kb and is in fact a zip archive: $ unzip -l example.docx Archive: example.docx Length Date Time Name -------- ---- ---- ---- 573 09-05-13 05:29 _rels/.rels 531 09-05-13 05:29 word/_rels/document.xml.rels 208 09-05-13 05:29 word/settings.xml 845 09-05-13 05:29 word/document.xml 1903 09-05-13 05:29 word/styles.xml 595 09-05-13 05:29 word/fontTable.xml 379 09-05-13 05:29 docProps/app.xml 476 09-05-13 05:29 docProps/core.xml 1118 09-05-13 05:29 [Content_Types].xml -------- ------- 6628 9 files Files like this shouldn't be opened with Ada.Text_IO. I bet that if you create your plaintext using Notepad (maybe even Wordpad) you wouldn't need to go through AdaGIDE to create a file that your program *can* open.

Hi Simon,

I have just tried doing that in NotePad and it sailed through - I wrote this short passage -"The rain Spain is maily in the plains." - effortless encryption -

Many thanks to you and everybody for this great help - I think you will appreciate how important it is to go public and being totally confident - this is new cryptography and it is a world first in vector based cipher design - I am very pleased it is in Ada also - This puts me in the driving saet with total confidernce now i.e. knowing what answers to give users who may ask.

Cheers - Austin
