/*Asm labels can only be defined once
in a task.  <F5> will spawn a new task
each time, so you don't get redefine
error, like when repeatedly #including
it from the cmd line.

These are many useful kernel
routines ::/Kernel/StrA.HC
intended to be called from
asm.  Generally, they preserve
regs.

You can call any routine you
like, C or asm, if you import it.
Be aware that C routines do not
preserve RAX,RBX,RCX,RDX,R8,R9.
When calling from the shell or
from C, preserve all other regs.
