It is only allowed global variables?

Hi everyone, i have the 4.057 compiler and i'm using his IDE.

So... everytime i put a local variable (inside the main()) i get the error:

hi everyone...

another thing that is going wrong is that i'm trying to print a int16 (as decimal unsigned int, i.e. using %d) over the serial and i'm getting the error:

There is no way anyone can help you without seeing your code.

Please post the section of code where you are having problems and the variable declarations.

To print an int16, the format specifier is %ld. It always was. The new compiler though _warns_ you that the format is wrong. Some older ones didn't.
Local variables behave just as they have always done. Any variable declared inside a function is local. You need to post an example, so we can see what is wrong.

For the 'numeric value' error, look for a mismatch in braces ( for every { you need a } ), misplaced semicolons, other typos above where the error occurs.

It's hard to answer the question without seeing the code...

You must put all declarations at the beginning of the function before everything else.

thanks everybody for the help...

the display error was only the lack of the L...

and about the variables... well, i noted that the compiler not permitted if the definition is inside the while(true) (i guess that makes sense), is just put inside of a condition test (if) that it is allowed

again, thanks very much
