[ROM Call]
Index=$EC

[Description]
Checks pressing of BREAK key.

[Explanation]
OSCheckBreak returns <A HREF="$$LINK(alloc.h/Bool)">TRUE</A> if BREAK key was pressed
(for this, BREAK must be enabled using <A HREF="$$LINK(system.h/OSEnableBreak)">OSEnableBreak</A>),
else returns <A HREF="$$LINK(alloc.h/Bool)">FALSE</A>. Note that OSCheckBreak will
remain true until explicite call of <A HREF="$$LINK(system.h/OSClearBreak)">OSClearBreak</A>.
