how to print a doc file

You could use the Automation Data Type.

Create the following vars:

Name          DataType       Subtype
Word          Automation     'Microsoft Word x.0 Object Library'.Application
Selection     Automation     'Microsoft Word x.0 Object Library'.Selection

Then you have to code something like the following:

CREATE(Word);
Word.Documents.Add();
//if you want to use a template; Template has to be a text var
//Template := 'C:\template.doc';
//Word.Documents.Add(Template);

Selection := Word.Selection;
Selection.TypeText('Test');

Word.Visible := TRUE;

//to print the document on preset printer
Word.PrintOut;

Of course you can use a template, so you just have to fill in the needed information.

The "Selection" is just an alias for "Word.Selection". But the Selection var has to know which selection it should control. So you have to assign the Word.Selection to the Selection var.

You could also control everything with the Word var.

Selection := Word.Selection;
Selection.TypeText('Test');

is the same as

Word.Selection.TypeText('Test');
