Using ATL (Active Template Library) you can certainly have HTML windows in LB/LBB. For example this, adapted from one of Alyce's programs, illustrates color and layout achieved that way:
Code: nomainwin
WindowWidth=400
WindowHeight=300
menu #main, "&File","E&xit", [quit]
graphicbox #main.g, 0, 0, 100, 100
open "Liberty Basic ATL Demo" For Window_nf As #main
#main "TrapClose [quit]"
Open "atl" For DLL As #atl
CallDLL #atl, "AtlAxWinInit", Ret As long
hWndViewer = hWnd(#main.g) 'Windows handle of graphicbox
hMain = hWnd(#main) 'Windows handle of main window
STRUCT Rect,_ 'struct for storing client area rectangle
leftX as long,_ 'upper left x
upperY as long,_ 'upper left y
rightX as long,_ 'lower right x
lowerY as long 'lower right y
calldll #user32,"GetClientRect",_
hMain as ulong,_ 'window handle
Rect as struct,_ 'name of struct
r as long 'return
cw = Rect.rightX.struct
ch = Rect.lowerY.struct
'resize graphicbox to fill client area of window
#main.g "locate 0 0 ";cw+2;" ";ch+2
#main "refresh"
CallDLL #user32, "GetWindowLongA", _
hWndViewer As ulong, _ 'handle of graphicbox
_GWL_HINSTANCE As long, _ 'flag to get instance handle
hInst As ulong 'returns instance handle of graphicbox
style = _WS_CHILD or _WS_VISIBLE or _WS_VSCROLL
'a minimal HTML document:
html$ = "MSHTML:<html><head></head><body>" + _
"This is an <font color=red>HTML</font> window!" + _
"<p><center>This line is centered</center>" + _
"</body></html>"
CallDLL #user32, "CreateWindowExA", _
_WS_EX_STATICEDGE As long, _ 'extended type
"AtlAxWin" As ptr, _ 'class name
html$ As ptr, _ 'URL, or progID or CLSID
style As long, _ 'window style
0 As long, _ 'left x pos
0 As long, _ 'top y pos
cw As long, _ 'width
ch As long, _ 'height
hWndViewer As ulong, _ 'handle of parent = graphicbox
100 As long, _ 'handle to menu or child window ID
hInst As ulong, _ 'parent instance handle
0 As long, _ 'window creation data
hATL As ulong 'handle of active template library control
wait
[quit]
Close #main
close #atl 'close DLL after closing window
end
As far as navigation is concerned you can include links, but they will open a URL which may not be what you want.
It would be pretty easy to incorporate the above functionality as one of the predefined window types in LBB, i.e. something like:
Code: open "HTML demo" for html as #main
(not that I have any plans to do so).

Yes.
Exactly like this but an example for the same with BBC4MAC.
Can't we make similar system calls with MAC OS-X?
Anyway, I think BBC for MAC is awesome and I like to see system calls similar to this ATL Browser example for Win32.

Thank you Richard!
I'll have to play with the ATL.

This would be awesome!
Currently I am creating HTML files with my LBB programs so that my folks can navigate them as web pages (My work will not allow me to use a web server to serve PHP pages).
So, I am trying to create the "web experience" they are used to, without actually running a web server. Just static web pages created from LBB.
It works pretty good, but it would be nice if I could have my program running in the HTML window, since now it's a bit awkward doing it the way I am.
RUNBASIC is close to what I would like to see, but even it is creating a server to serve the pages.
I'm looking more for something I can send out as just a executable that "feels" like a web page in how it functions for the users.

Of course you can make system calls, but I have no idea whether the Mac exposes an embeddable browser or HTML control in any way similar to ATL. You would need to ask an OS-X expert about that.

Why don't you simply bundle the pages with your application as straight .html files (LBB would allow you to embed them in the EXE file of course) and then point the local browser at them? Most, if not all, popular browsers support the file:// protocol I think (I've just tried Edge, FireFox and Chrome and they all seem to) so you shouldn't need an HTTP server like Run Basic.
Somewhat to my surprise even the ATL embedded browser control seems to understand the file:// syntax, although for some reason it was awfully slow at fetching the page across my home network.

Yep, one of the drawbacks for the file option. It works, but is painfully slow.
My HTML files are dynamic based on the program output. It's not like I am just accessing a bunch of static HTML files because they look pretty.
I would rather my program have input boxes on the HTML window (like a real form entry), then redraw the HTML page based on the database results, etc...
So essentially it would resemble typical HTML functionality, but being interpreted from the engine of LBB and not a server.

I would suggest you check out Microsoft's IWebBrowser2 control to see if it has the capabilities you need. Because it uses an Object Oriented (COM) interface you would need to use the CallMethod function I wrote in order to access it from LB/LBB:
Code:function CallMethod(object, method, parm$)
code$=chr$(139)+"D$"+chr$(4)+chr$(139)+"T$"+chr$(8)+chr$(139)+"L$" _
+ chr$(16)+"VW"+chr$(139)+"t$"+chr$(20)+chr$(43)+chr$(225)+chr$(139) _
+ chr$(252)+chr$(243)+chr$(164)+chr$(80)+chr$(139)+chr$(0)+chr$(255) _
+ chr$(20)+chr$(144)+chr$(95)+chr$(94)+chr$(194)+chr$(16)+chr$(0)
p$=parm$
n=len(p$)
calldll #user32, "CallWindowProcA", code$ as ptr, object as long,_
method as long, p$ as ptr, n as long, CallMethod as long
end function
