Control of Engineering Software

As the code is compiled, the compiler may identity syntax errors, and the programmer can correct these. Sometimes, one statement or portion of a module will be continually rejected by the compiler. When this happens, it is a good practice to "dump" the module and get a hardcopy printout for detailed examination. Compiling and debugging is an interactive process which must be continued until all statements in the module have been successfully compiled. A word of caution is an order at this point. Successful compilation is only the first step along the path to quality output. It does not mean the program code is free from faults. Remember—neither the compiler nor the computer hardware can recognize an error in logic. If the program says black is white, the computer will accept it.

Syntax error, often called parser error, is a type of error when parser gets a set of codes that violate the rule of a language [1]. This is the most common type of error in Python. Any mistake in proper syntax generates an error like the one shown in Figure 18.1. Such errors are also highlighted with an arrow so that one can easily detect the point where the error actually occurs. For example, if the colon: used at the end of the while loop is missing, the arrow points to the statement immediately after the whileloop. In case of IDLE Graphical User Interface, the error message is not displayed directly in the console; instead it shows a message dialog box as illustrated in Figure 18.2.

Syntax errors can be considered grammatical errors and are typically the easiest to locate and fix. Because the compiler cannot translate code that is not in the correct syntax into machine code, the compiler will detect these errors and will not successfully compile until the syntax errors are resolved. Typically, when a syntax error occurs, the compiler responds with an error message that indicates what line in the code contained the error. Because one syntax error can generate several error messages, it is recommended that you start with the first error, repair it, and then compile again. Often, repairing one error will resolve a number of error messages.
NewSQL Database Management System Compiler Errors: Effectiveness and Usefulness
Published in International Journal of Human–Computer Interaction, 2022
Next, a participant was randomly assigned to one of the four database management system groups—i.e., CockroachDB (n = 32), NuoDB (n = 44), SingleStore (n = 39), and VoltDB (n = 44)—and shown a set of 20 tests, one test at the time. The first four tests were control questions measuring participant skill in error fixing, and these four tests were the same for all participants, regardless of the group the participant was assigned to. Next, the test suite of 16 tests (cf. tests T01–T16 in Table 1) was shown, test by test, and in a randomized order for each participant. Each of the 16 tests consisted of a database structure diagram, a data demand, an erroneous SQL query, an error message generated by the DBMS, a free text input box in which the participant was instructed to write the fixed query, and a set of five-point Likert scale (1 = strongly disagree, 5 = strongly agree) questions pertaining to subjective indicators of the usability qualities of the error message (cf. hypotheses H2, H3 and H4 in the next section). Depending on the group the participant was assigned to, they were shown corresponding error messages, e.g., for participants assigned to VoltDB group, VoltDB generated error messages were shown. Answering could be paused or stopped altogether, yet none of the participants chose to do so. The participants could use any materials for support during the tests. For more details on the tests, error messages, database structure, and questions, please refer to the supplementary Appendices. After all the participants had answered the tests, the first author coded the queries submitted by the participants as correct or incorrect. A query that contained at least one syntax error was considered incorrect.

Verification of the model was performed using both code and calculation verification and visual confirmation of the model. The results of running the model with Arena software show no syntax error in the model. This condition indicates that code verification has been met. The results of several calculations (i.e., lost sales and order fulfilment rate) in the model are per the formulation. The visualisation results also show that the simulation animation has run according to the input logic and algorithms.
