Solution

• Create a Word document which will serve as a template for the final document
• For the variable parts use placeholders &[xxx] where xxx stands for the name of a GuiXT variable
• For GuiXT text variables use &text[xxx] where xxx stands for the name of a GuiXT text variable
• For Word tables put placeholders &[xxx.###] into the cells. Here ### will be replaced with the row number 1,2,3,... to form a GuiXT variable name xxx.1, xxx.2, ...
• Save the Word document as .rtf file, e.g. mytemplate.rtf
• In your InputScript, use CopyText ... fromTemplate="mytemplate.rtf".
  The template file is read and your placeholders are replaced with the content of the  GuiXT variables. New table rows are added as long as a GuiXT variable with the corresponding row number exists for the first column
• Save the file as .rtf file or .doc file

Remark
The placeholders &[xxx] must not contain any inner formatting, for example &[xxx] (first 2 xx in bold). It is important that the placeholder strings appear in the form &[xxx] in the resulting template .rtf file.
If a placeholder is not substituted by the value of the corresponding GuiXT variable, copy the whole placeholder string &[xxx] into a simple editor such as "notepad", delete the string in Word and copy the string from notepad again into the Word document. This removes any inner formatting of the placeholder string.
If you open the rtf file with notepad, a wrong placeholder looks like
&[rtf.c}{\rtlch\fcs1 \af1 \ltrch\fcs0...
instead of
&[rtf.cn]
for example.

Example
We generate a Word document that shows all customer orders for one month.


Template file

The upper part of the page, including the column headers, is within the page heading of the Word document so that the column headers are repeated on each new page.

Result

// read customer orders as database join of VBAK and KNA1
