I have a couple of simple macros that I use a lot and that may be useful to others. They extend the use of .while -- .endw

.break This macro within a .while loop breaks the loop and resumes at the instruction following .endw
Note that .while is happy with no parameters.
.cont This macro stops processing and loops back to the .while instruction.

The macros are:
macro .break { jmp __ENDW }
macro .cont { jmp __WHILE }

See also fasmx - .while with .break .and continue
Also includes .break .if and .continue .if

Thanks for that info, I was not aware of them.
Are they documented anywhere?
(I wonder if the wheel was invented more than once ...)
