Using Word bits

Thad

Hi All,
·I am trying to use the lookdown command to set some bits in a word variable but it seems that the word variable type does not allow a variable index beyond 7 with this command.

CMDBITS················· VAR· WORD
GP·························· VAR· BYTE
GP1························ VAR· BYTE

LOOKDOWN GP, "1","2","3","C","P","?","0","Z","R","W","S","V","t", GP
··CMDBITS.GP = 1

When compiling for an SX48, the error is:
· Expected a Value between 0 And 7 "GP"

Is there a fix or workaround for this?

Thanks
Thad

You'll have to make a mask for the bit you want to set.

tempWord = 1 << GP
CMDBITS = CMDBITS OR tempWord

Ok, I guess I'm confused.
I thought this command
·LOOKDOWN Target, Value0, {Value1, Value2, ...} Variable

Returned to Variable·a value based on the matching position in the value·list.

In the example·CMDBITS.GP = 1 the GP would be an offset in number of bits. Is this not the case?

Thad,
Your right, but on the SX the bit position cannot be a variable.
That's why you're getting an error on that line.

Hi Bean,
· Ok, Thanks. The SX manual isn't clear on what can be a variable and what can't.
