Is the Output of the Program Incorrect?

Incorrect program output typically indicates a flaw within the logic of the code. To help find the error:

• Set a breakpoint in the code prior to the point where the bad output is produced.

• Step through the ER line by line, while monitoring the values of relevant ER variables.

  At some point, a variable will probably take on an erroneous value that subsequently produces incorrect output.

• If that point occurs before your breakpoint, set another breakpoint earlier in the code and restart the application.

• Continue this process until you find the statement that is causing the wrong value to be assigned to the variable.
