3.13 BASIC Program Priority Order (Priority)
In the QD51 (-R24), a priority order (priority) can be assigned to BASIC programs that
are created.
When BASIC programs are started, all BASIC programs are set at the same priority
order.
Therefore, the BASIC programs created by the user are run equally.
The priority order can be changed by the ZURGENCY command.
If the priority order is changed, as long as a program execution switch command is not
run, only the BASIC program with the highest priority is run without any scheduling
being done by the OS.
(BASIC programs with a low priority are not run.)
