If you change this to a 1 (I assume that '1' = use BSR to select GPR bank = BANKED), then it compiles ok. #8 nickoatley Starting Member Total Posts Java tells you where it discovered that your program had gone wrong, but you need to trace back from there to figure out where the problem originated. ldi ZL, low (cmdtable * 2) ldi ZH, high (cmdtable * 2) .if ((cmdtable * 2) > 65535) ldi r16, 1 sts RAMPZ, r16 .endif ; more code follows here cmdtable: Syntax Error Java Result of dividing by zero.

Thus all of the lab projects in all of the other lessons serve as the lab project for this lesson. Syntax Error Example The classical divide by zero error The classical way to demonstrate a runtime error is to instruct the computer to divide any number by the value zero. [next] [tail] [up] C.13.1 General assembler errors Divide by zero in asm evaluator This fatal error is reported when a constant assembler expression performs a division by zero. find more This will lead you to where the error must have occurred.

This is reported when you try to use a non-label identifier with an '@' prefix. Logic Error Example Syntax errors are those which are caused by incorr…ect usage of the programming language. I liked using the ASM blocks as well since it was less verbose then typing in the asm("..") every time, so not sure what the reasoning is here. In: Hillary Clinton Answer it!

Logic Error The syntax error is shown in the editor, along with the error code. Syntax Error In Programming Evaluator stack overflow, Evaluator stack underflow These fatal errors are reported when a constant assembler expression is too big to evaluate by the constant parser.

Put in print statements to help you figure out what the program is actually doing. http://3cq.org/syntax-error/what-is-a-syntax-error.php However, it is unlikely that you will understand the explanation of what went wrong, because that explanation is given in terms of the underlying Java language. The only way to use inline assembler that worked for me is asm("...");It happened to me while building Microchip HID bootloader for PIC18F14K50, in UnlockAndActivate function. The exact behaviour of DEFINED(symbol) currently (from 2.1.5) is:The preprocessor 'defined' keyword only relates to symbols defined with #define, and correctly does this only in preprocessor conditionals (#if/#elif).In all remaining code, Semantic Error
