1. 5250 Applet Cannot Display DBCS Characters Correctly Which Are Input From Keyboard (Win32)

SYMPTOMS

The Win5250.exe program did not display DBCS characters correctly when they were typed on a keyboard. This did not occur if using cut and paste.

CAUSE

The Win5250 applet was processing VK_PROCESSKEY code when it receives WM_KEYDOWN message on Win32 platforms.

RESOLUTION

The Win5250 applet now ignores VK_PROCESSKEY when it receives WM_KEYDOWN messages.

STATUS

An update to SNA Server 3.0 is available to correct this problem.

1. 5250 Applet Terminates Trnsdt.dll When It Exits (Win16)

SYMPTOMS

When the 5250 Applet exits, it terminates Trsndt.dll even if another module is calling TrnsDt. This problem occurs only in Windows 3.x (16-bit) using the Windows 3.x SNA Server client. It does not occur when using any of the 32-bit clients.

CAUSE

Win5250.exe issued FreeLibrary API to the same instance twice when it exited.

STATUS

An update to SNA Server 3.0 is available to correct this problem.

1. 5250 Applet Displays Shift-Out Code (All Platforms)

SYMPTOMS

When DBCS data is input from the keyboard, the 5250 Applet displays the shift-out code (0x0e) directly. It should be converted to a space (0x20) character.

CAUSE

The Win5250.exe program was displaying the EBCDIC shift-out code incorrectly.

STATUS

An update to SNA Server 3.0 is available to correct this problem.

1. 5250 Applet Has a Fixed Font Name (All Platforms)

SYMPTOMS

The 5250 applet is unable to display Japanese messages on the status bar.
