    Other than capturing the image in a dos-session, is there any way to display the ASCII characters below decimal 32 and above decimal 127?

    This is strictly a function of which characters are supported by each Windows font; it's not a problem that is specific to PB/CC or PB/DLL programs.

    If you are using PB/CC, try changing the console font from "bitmap" or "raster" to "TrueType". Or vice versa... I forget which one does not support all 256 characters. Also, under certain circumstances you may need to change the console font before the characters are displayed.

    If you are using PB/DLL, you'll need to use a font that supports all of the characters you need.

      Use %OEM_FIXED_FONT (Terminal) or TTF "Lucida Console" (more nice, but 0-31 + not sure about W95).
         #Compile Exe
         #Register None
         #Dim All
         #Include "WIN32API.INC"
         CallBack Function DlgProc
            Select Case CbMsg
               Case %WM_PAINT
                  Dim hDC As Long, hFont As Long, i As Long, j As Long
                  hdc = GetDC(CbHndl)
                  Local lf As Logfont, lResult As Long
                  lResult = GetStockObject(%OEM_FIXED_FONT)
                  GetObject lResult, SizeOf(lf), ByVal VarPtr(lf)
                  ' change height/width
                  hFont = CreateFontIndirect(lf)
                  SelectObject hDC, hFont
                  Dim z As String * 16
                  For i = 0 To 15
                     For j = 0 To 15
                        Mid$(z, j + 1, 1) = Chr$(i * 16 + j)
                     TextOut hdc, 0, lf.lfHeight * i, ByVal VarPtr(z), 16
                  ReleaseDC CbHndl, hDC
                  DeleteObject hFont
             End Select
          End Function
          Function PbMain
             Local hDlg As Long
             Dialog New 0, "OEM",,, 200, 200, %WS_CAPTION Or %WS_SYSMENU To hDlg
             Dialog Show Modal hDlg Call DlgProc

        DOS uses an extended ASCII character set, also referred to as the
        OEM character set. The characters above 127 are locale-dependent
        (they may differ in different countries). In Windows, you are most
        likely to use the ANSI character set, which is similar but not
        identical. To translate from one to the other, use the Windows API
        functions OemToChar and CharToOem. It is not always possible to do
        a perfect translation from one character set to the other. This
        depends, in part, on the Windows font involved, as some fonts are
        more ANSI-compliant than others.
