And, if possible, your SUB for the time-display thread ?

I think we will not be able to help you successfully if you do not provide us with your current full code.
(I am afraid that in the main thread, INPUTSCREEN uses the INPUT keyword that so must compete with output keywords in the time-display thread)

@mark bower, General remark on some of your previous codes: Inside any [Mutexlock...Mutexunlok] block (or any [Screenlock...Screenunlock] block) of any thread (main thread and user threads), never place an ending instruction as 'If ... Then Exit ...' because the mutex remains locked (or the ...

For the beauty of the thing, don't forget to destroy the mutex at the end (only when the thread is finished):

Note: - [Screenlock...Scrennunlock] blocks are not compatible with multi-threading (otherwise, the program hangs). This is why a mutex block must be used around each such block to ensure the mutual exclusion. - The input keywords (like for keyboard, mouse) cannot be safely run when the screen is lo...

Simple example but only working with a mutex: (I don't see how to make it work without mutex) Dim Shared As Integer x, y, wheel, buttons Dim Shared As Boolean quit = false Dim Shared As Any Ptr pmutex Dim As Any Ptr pthread Sub Thread (Byval p As Any Ptr) Do Mutexlock(pmutex) Getmouse(x, y, wheel, b...

I never tried it because I don't think it works.

Beware when using SCREENLOCK with multi-threading: - The screen is locked by stopping the thread that processes also the OS' events. - Thus, when the screen is locked, all other threads are stopped up to the screen unlocking. - Only runs the thread which has locked the screen. This behavior occurs ...

Could you point us to the corresponding topic(s) in the forum?

#attach# / #detach# ?

OKAY.
(I think in each of your two examples above, 'print y' should be replaced with 'print x', because '@x' is the destination address and '@y' is the source address)

@JK But if we ever keep it, I wish it had the same type of declaration as the current POKE: declare sub poke any ( byval pdst as any ptr, byval psrc as any ptr, byval bytes as uinteger ) Consequently 'poke any, pdst, psrc, bytes' would act as 'fb_memmove( byval pdst , byval psrc , bytes)'. ??? By sp...

Is your question about the paragraph "Creating a Text View Port" at page 213 of the "A Beginner’s Guide to FreeBasic" book ?
If yes, see also VIEW PRINT.
