Well, the imported (dropped) file does not contain these strings then I am only
setting the text of a field to the collected lines (tNewLine) after the repeat loop:
put item 9 of tLine into item 6 of tNewLine

Hm, the debugger also has this problem and the bug does not seem to be fixed yet:

OK, anyway, do you have a hint on how to debug this with my 60000 lines file?
I checked the "item 9" (see above) and even "item 6 of tNewLine" after the line above for scientific notation, 
no dice, I can only see this behavior in the field after I filled in the new data?

Will keep on exploring...

For example, the variable viewer in the SE is a treeview widget, so if a variable holds a number that will display in scientific notation if it has above a certain number of significant digits.

Thanks for chiming in!
