    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.

    Use %OEM_FIXED_FONT (Terminal) or TTF "Lucida Console" (more nice, but 0-31 + not sure about W95).
    Code:
       #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)
                   Next
                   TextOut hdc, 0, lf.lfHeight * i, ByVal VarPtr(z), 16
                Next
                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
        End Function

    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.

    started a topic ASCII

    ASCII

    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?
