Bitwise Encode Problem

T Chap

Can someone please help me understand why the following produces an 'expected end of line' error:

word  KPBPinInput
byte adminpw[noparse][[/noparse] 3]

adminpw[noparse][[/noparse] 3] := >|KPBPinInput

The KPBPinInput contains any possible input from a keypad read with I2C into the word var. I want to convert the keypad bitfield into its corresponding number, and according to the manual:

PinNum := >|Pin
The above example sets PinNum equal to the number of the highest bit set in Pin, plus 1.

Thanks for any suggestions

It looks like you allocated three bytes for storage.

You can use index 0, 1 and 2 but not 3.

Maybe there's something else...

Thanks, I have experimented with variations, allocating doesn't fix the error.

mynet3 is right, but that's a semantic error. The error being reported is a syntax error. Based on what little you've shown, you should not get such an error, but there's a lot of context missing. So, without seeing the rest of your code, it's impossible to say where the problem is.

Oops sorry guys, this appears to be a BST issue, compiles on Proptool.

Thanks for the help.

Here's a test case I wrote:

VAR
  long UserNumber, testlong

PUB Init

' init vga display

  testlong := %1000_0000_0000_0000_0000_0000_0000_0000
  repeat
    testy

  repeat

PUB testy
  UserNumber := >|testlong
  vga.cursloc(40,30)
  vga.dec(UserNumber)

It works perfectly and displays the number 32 over and over...

Can you show me how to reproduce it please? I've not been able to here.

Hey Brad

I recall that there was a recent save that gave a warning about unicode, although I don't know why.

When I opened the file in Proptool, it said invalid characters found and the offenders were highlighted in white, simply a blank space between "UserNumber" and ":=", I backspaced over the space, then hit the space bar again, then it compiled fine. I saved it, reloaded in bst and it is fine. Some how a space became invalid, but I have no idea how. Easy fix though, need to pay heed to the unicode flags in the future.

Fab, thanks [noparse]:)[/noparse]

I now know to double check the Unicode stuff around the editor and see if I can get something non-standard to happen.
