GetBit Compile Problem

RS_Jim

@Bean,
I have the following piece of code that does not want to compile:

Flags VAR Byte
AdoneX Var Flags.5

DO
tmpw1 = $FFFF
·GetBit Flags,5 ,__param5 'line wont compile
·IF __param5 <> 0 THEN
··AccResult = ACC_RESULT
··ATIme = __wparam34
··tmpW1 = DACC
··TX_BYTE tmpW1_MSB
··TX_BYTE tmpW1_LSB
··TX_STR CRLF
·ENDIF
Loop
I get invalid parameter· __param5
If I change it to GetBit Flags, AdoneX, __Param5 I get same error
if I change it to GetBit Flags,.5,__param5 I get invalid Number of Params
what is wrong with my GETBIT Request?
If i comment out the Getbit, the program compiles/assembles no problem.

Jim,
I guess I need to add to the documentation.

The 3rd parameter must be a bit variable, and the 2nd parameter cannot be a constant. Because then you could just use __PARAM5.0 = flags.5.

I would change your code to:

PARAM5 = flags.5

Does that byte of memory hold "A", 65, $41 or %01000001 ?
Yes it does...

OK, that compiles correctly, Now I am not sure why I would not just use __param5.0 = Adonx if I needed it in Bit 0. I am just
testing to determin if the flag has been set before preforming the next step so a 0/<>0 result is all I care about.

You can test a bit directly:

IF flags.5 THEN
  ' code runs if flags.5 = 1
ENDIF

For zero you would do this:

IF flags.5 = 0 THEN
  ' code 
ENDIF

Great JonnyMac,
so if a Have an alias for flags.5 then:

IF adonex = 1 then
'code
ENDIF

or
IF adonex = 0 then
'code
ENDIF

if this works I can do a great thing with my code,

That syntax will work, I use it all the time. Just create the alias in your variables declarations.

RS_Jim

Cool, The declaration is already done.
