read OUT staus

Hi All,
Can anyone please comment on this statement. I can not seem to get it
to work.
Result var byte
if outs(result) then display
I have also tried if outL(result) then ...
I have also tried if out0(result) then...
I don't think that the out statment works if followed immediatley by
a variable representing a pin number (1, 2 or 3 etc). If I use out1
or out2, I can read the pin status. However reading 24 pins takes up
too much code this way.
Can I assign a variable such as "result", which represents a pin
number, to the out statment?
I simply want to read the status of multiple outputs and display the
status.

OUTS is a word-sized variable at memory location 2. OUTS(result)
refers to a word of memory at location 2 + (result * 2), memory
which you have probably declared for use by other variables.

Try this as a stand-alone program:
i VAR WORD
j VAR BYTE
FOR i = 0 TI 65535
OUTS = i
DEBUG CR,HEX4 OUTS," "
FOR j = 15 TO 0
DEBUG BIN1 OUT0(j)
NEXT
NEXT
This cycles OUTS through all possible values, reading each output
latch individually as an array member. It works.
It may be that your program is not setting the output latches
to the values you intend, which causes unexpected OUT0(value)
results. To verify this, add this statement to your program at the
point where you are testing the OUT0(value) settings:
DEBUG CR,BIN16 OUTS," ",DEC value
This will show you the current value for all 16 output latches and
should match what you are seeing via the OUT0(value). It will also
show the actual quantity contained by your "value" variable, which
may not be what you intend/expect--another reason OUT0(value) seems
wrong.

You can assign outs to a variable, like this
Result var word(2)
K var byte
Bitvalue var bit
Mainio
Result(0) = outs
Auxio
Xresult(1) = outs
For k=0 to 31
pinvalue = result.bit0(k) 'get value for single pin
debug bitvalue+48 'display 0 or 1
next
Hope this helps
Regards peter
