New Features

Features in version 5.3

  • Moved the platform to Visual Studio 2019 (with intent of implementing TLSv1.3)
  • Replaced MS Visual C++ Redistributable (2015) by Microsoft Visual C++ 2015-2019 Redistributable (x86) 14.25.28508.3
  • Added Signature Algorithm, Encryption Algorithm to Certificate Info popup (Secure version only)
  • Removed obsolete Auto-update function


New Features in version 5.2

Installation issue in multi-user environment (RDS, Datacenter 16)

Description: When installed under one user’s account, then 2nd user tries to run QWS3270, control switched to unsolicited install

COM Automation DLL 64-bit

Description: Fixed discrepancies in shared memory between 64-bit DLL and QWS

Added type-ahead (paste-ahead) when keyboard is locked.

Description: When user pastes text from the clipboard while the keyboard is locked (waiting for the mainframe application to respond), it immediately pastes the text on the “locked” screen. After the change CTRL-V is buffered, and delivered to the screen after keyboard is unlocked. Useful in (for example) search scenarios: “Copy text” + F + CTRL-V + “more text”

WHLLAPI calls logging

Description: Users reported that Automation screen scraping was broken under 5.x, especially for 64-bit Automation DLL. Troubleshooting from COM Automation application (e.g. Excel VBA macro) or application utilizing JGSComdotNet, or direct HLLAPI calls was insufficient.


Also a layer of logging was added to COM Automation DLL-s, since the cause might be Automation DLL, not necessarily HLLAPI.

Added handling of multiple variables in JG Script commands.

Description: Prior to the change, command (e.g. Message) with global/local var worked only if message started with var (i.e. “%USERID% is the user” – works. “User is %USERID%” fails. Apparently multiple vars are not being handled as well. For example, “%var1% abc %var2% def” will not be parsed and executed properly.

    QWS3287 (printer app) to install package

    Description: Printer app component was missing, starting early releases of 5.0
    Solution: Added “as of 2013 QWS3287” printer app and compatible DLL-s as a separate resource to Wix. Printer app is being installed under “C:\Program Files (x86)\QWS3287”.

    Colors not saving properly in session

    Description: Fixed “Customized color files for a session are not being saved” issue


    QWS3270 product property (Task Manager, EXE properties)

    Description: product property (Task Manager, EXE properties) was showing just PLUS
    Changed product property, so it reflects SECURE/PLUS

      Windows Features
      • Choose between blinking and non-blinking cursors. A Crosshair option to visually assist with text alignment is also available.
      • Clipboard Support for the common copy, cut and paste functions. It also provides an APPEND function where data can be appended to data already in the clipboard. A PRINT function allows the clipboard data to be sent to the Windows printer
      • Cursor customization including underline, block and vertical bar. A different shape can be displayed when in insert mode.

Word Wrap automatically does a New Line function for you when you need a new line. Word wrap picks up any partially typed word and places it on the next line.
