Can anyone please give a proper guideline as to how to deal with this application?   Thanks Fri, 08 Jun 2018 16:36:00 GMT https://community.blueprism.com/t5/Product-Forum/MainFrame-QWS3270-Application-integration/m-p/55953#M10218 SankarlalM 2018-06-08T16:36:00Z https://community.blueprism.com/t5/Product-Forum/MainFrame-QWS3270-Application-integration/m-p/55954#M10219 If you search for Mainframe in the knowledgebase (now accessible via a ? button at the left of the Portal) you will find an article titled 'How do I connect to my uncommon mainframe emulator?' Your mainframe needs to be hllapi compliant (something all the enterprise terminal emulators are) - if it is not I would recommend your organisation looks to get an emulator that is hllapi compliant as it will pay for itself in speed of development and runtime when compared to using surface techniques against a non-compliant emulator.
