I apologize but I don't fully understand your question and I do need more information. I am not sure if you are talking about the Origin main menu item File:Import:ASCII, the Script Window menu item File:Open, or running an *.OGS file that attempts some sort of file import.I was able to import a *.OGS file (in both Win 95 and Win NT) using the Origin main menu item File:Import:ASCII after setting all ASCII import options (File:Import:ASCII Options). Basically, I explicitly specified all import parameters to precisely fit the text file rather than relying on Auto-determination and then imported the file into a worksheet column of type Text. The Script Window menu item File:Open only imports files of type *.TXT and will not import *.OGS files in either operating system. Finally, I wrote a small import script
[Import]
getfile *.TXT;
open -w %B%A;
and placed it in the file TEST.OGS. It ran fine in both Win 95 and Win NT when executed by the command
run.section(Import,Test);
I hope one of my three guesses answers your question. If not, I recommend contacting you Origin dealer and requesting technical support. Be sure to provide as many details as possible including which menu item and/or LabTalk commands are used.
