[Function] Write the value in variable 99 to the output ports or flags from the one specified in operand 1
for the number of digits specified in operand 2 as a BCD.

(Note 1) A maximum of eight digits (32 bits) can be output.
(Note 2) The number of output ports and flags that can be used is 4 x n (digits).
(Note 3) The write data format can be changed using a FMIO command (refer to the section on FMIO
command).
[Example 1] OUTB 300 2 Write the value in variable 99 to the output ports from
300 for two digits (until output port 307) as a BCD.
[Example 2] LET 1 300 Assign 300 to variable 1.
LET 2 2 Assign 2 to variable 2.
OUTB *1 *2 Write the value in variable 99 to the output ports from
the content of variable 1 (output port 300) for the
content of variable 2 (two digits) (until output port 307)
as a BCD.
