Optional Optional INB Output, flag BCD digits CC
[Function] Read the I/O ports or flags from the one specified in operand 1 for the number of digits
specified in operand 2, to variable 99 as a BCD.

ON OFF OFF OFF OFF ON OFF ON
85 Variable 99
(Note 1) A maximum of eight digits (32 bits) can be input.
(Note 2) The number of I/O ports and flags that can be used is 4 x n (digits).
(Note 3) The data format used for read can be changed using a FMIO command (refer to the
explanation of the FMIO command).
[Example 1] INB 8 2 Read input ports 8 through 15, to variable 99 as a
BCD.
[Example 2] LET 1 8 Assign 8 to variable 1.
LET 2 2 Assign 2 to variable 2.
INB *1 *2 Read the input ports from the content of variable 1
(input port 8) for the content of variable 2 (two digits)
(until input port 15), to variable 99 as a BCD.
