#8 Must enable ANSI in Windows terminal

[Tom Wilson]

Windows 10 does not support ANSI escape sequences by default, so terminal commands like LOCATE and CLS don't work in BWBASIC.

Microsoft has info here on how to enable it:
https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences

The relevant code seems to be this:

// Set output mode to handle virtual terminal sequences
 HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
 if (hOut == INVALID_HANDLE_VALUE)
 {
 return GetLastError();
 }

 DWORD dwMode = 0;
 if (!GetConsoleMode(hOut, &dwMode))
 {
 return GetLastError();
 }

 dwMode |= ENABLE_VIRTUAL_TERMINAL_PROCESSING;
 if (!SetConsoleMode(hOut, dwMode))
 {
 return GetLastError();
 }

There is also a workaround, but this affects the behavior of all command line programs. I created a batch file that makes a registry change and launches the bwbasic environment:

REG ADD HKCU\CONSOLE /f /v VirtualTerminalLevel /t REG_DWORD /d 1
bwbasic

I would suggest advising users of the registry workaround and incorporating the SetConsoleMode command in a future release.
