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.

I have tried Word Pad also and iit works equally well - but as you say the file extension .doc is taboo - must not be used - .dat is fine

Summarising.

Users can use 'Notepad' with .dat file extension say
Users can use 'Wordpad' with .dat file extension

If users insist on using MS Word then it must go through the AdaGIDE editor with a .dat file extension (if any).

Thanks again - Austin
