535〇82 V. Description of the invention (7) It is the state of testing and debugging. _ The above-mentioned object is called Test Item or Test Routine. Its purpose is to define the control flow of a group of instrument control commands to achieve the purpose of automated testing. It is necessary to store the test items. ) Or the test routine (Test Routine), it will execute the "n translation" procedure. The so-called "translation" can basically be divided into 3 procedures. The first is to localize the user in the currently announced local (test setting parameters, test reading Value variables, temporary variables) and global variable names and types are checked one by one, and the variable names and types specified in each parameter of each test command are checked for their rationality one by one. Secondly, 5 variable tables are generated in the memory, including: test setting parameters, test reading variables, temporary variables, global variables and constant values. Finally, the variable or constant value specified by each parameter of the test command is interpreted as an index into the table. The test item (Test Item) or test routine (Test Routine) after the "translation" procedure has the advantage that when each test command of the test item (Test Routine) or test routine (Test Routine) is executed , It will directly obtain the reference position of the variable based on its index value to speed up the execution. The aforementioned "translation" is different from the Compiler or Interpreter of the programming language, because "translation" does not compile the source code into machine + device code. Before testing and debugging the control flow being edited by the user, the user must first successfully interpret it through "translation". Before the test item (T e s t Item) or test routine (Test Routine) is executed, execute the reference

When the execution engine executes a test item (Test itein) or a test routine (Test Routine), it will dynamically obtain the function indicator according to the name of each test command into the test command function library (DLL). According to the parameter content (type and number) specified by the user in this test command, it is packaged into a general type parameter string (this string supports variable length and the number of parameters), and then this test command is called . Test order

When =, the subscription engine can pass the current execution status to the test debug loop =. The user can set a breakpoint in a test command and view the contents of all the variables. The test command function library of the present invention is a dynamic link file (DLL). The ancestors can support more than one test command function library. As long as the function library that meets the test command function prototype is packaged into different DLL, however, in the editing environment and execution engine, different test commands are specified in the Test Item or Test Routine. The car body program can be executed without recompilation. Test and debug. Figure 9 shows the reading judgment status after the control process is completed.
