Please help me, I am coming up with and error message when I run a little program I am writing.

Here is the error message I get when I run the program:

"Expected, a label, variable or instruction."



Here is where the error message come form in the program******


DEBUG " Your time was ", DEC TimeCounter, ' Display time measurement.
" ms. ", CR
**** " To play again, hold the ", CR, ' Play gain instructions.
" button down again.", CR, CR


Thanks!!!

Not familiar with PBasic but I do write in VB.Net. The single quote character is used to denote a comment. The red text in your code above is considered comments.

You appear to be inserting comments in the middle of a DEBUG statement. That's usually not allowed. Also, there appears to be a missing comma after the first CR in the debug string.
Try this instead:

' Display time measurement and Play Again instructions
DEBUG " Your time was ", DEC TimeCounter," ms. ", CR, " ms. ",
" To play again, hold the ", CR, " button down again.", CR, CR

Finally, I would question the use of DEBUG as opposed to some other I/O method for interaction with the user (either a msgbox or a console.write or something along those lines).

I have programmed in regular BASIC which PBasic is based off of but it has been ages ago so its hard to remember the commands and syntax off of the top of my head but just looking through your code snippet I agree with djmilf.

I would insert the missing comma and remove the comments within the block. Try running it again and if no errors, put your comments before the block of code and run it once more to make sure you didn't introduce any new errors.

Thanks a lot. Pbasic does allow comments to the right of code, denoted with a '. Building a circuit along with the code, so debug is easiest. Cannot get through without that error, tried adding comma.

Thanks!

Thanks, tried that and still don't get through it. Pbasic allows comments to the right of code with a ' in front of comments.

I'm not familiar with PBasic, but have a couple of suggestions:

try removing the comma from within the following quoted string:
" To play again, hold the " << Since the comma is used to concatenate lines in the debug statement, it may need some special escaping, but I'm not sure.

The other thing to look at is the inconsistent use of commas. I'd check the following:

" ms. ", CR << All of your other lines have commas after them, but this one doesn't (and just happens to appear before the error).

Thanks, I have been playing with it, sentence structure is not that important. I'm kinda at a loss, moving commas and everything else aint doing it.

I don't have a board or I'd jump in a bit further here!

Several samples that I've seen follow the same syntax where they use a new Debug statement on each line, and end without a comma.

Give this a shot:

DEBUG " Your time was ", DEC TimeCounter ' Display time measurement.
DUBUG " ms. ", CR
DUBUG " To play again, hold the ", CR ' Play gain instructions.
DUBUG " button down again.", CR, CR

Yes, all versions of Basic allow comments to the right of the code - but they don't allow a comment within a statement.

A Debug is like a subroutine call and the items after the word DEBUG are like parameters. You're breaking up the parameter list when you allow a DEBUG statement to run on several lines and add comments to the right. The Basic interpreter will see it all as one line terminated by a comment.

Did you try it without the comments and with the correct number and placement of commas?

Thanks a lot, your suggestion was very close.

Here is the code that worked, basically your suggestion without the "Debug" command in every line (tried that and came up with error messages).

DEBUG " Your time was ", DEC TimeCounter, ' Display time measurement.
" ms. ", CR,
" To play again, hold the ", CR, ' Play again instructions.
" button down again.", CR, CR


LOOP



thanks a lot.
