天敌演员表刘新宇:谁能帮忙翻译一下这篇计算机文章?

It should be possible to place in each of these modules tracing procedures which indicate the flow of program control and the intermediate results progressively calculated by the program instructions. Maintaining the errors which existed in the given example, the algorithms for each module (after inserting typical tracing statements) would be:

(Given that the purpose of this last module is to print the contents of all associated variables, it is hardly necessary to insert additional tracing instructions.)
The tracing output from the processing of, say, the third and fourth test records as shown below should, when compared to the expected results already calculated, point out the existence of several errors in the program:

From the trace output the programmer can ascertain that some modules work correctly each time (e.g., COMPUTE PAYABLE HOURS), some work incorrectly sometimes (e.g., COMPUTE GROSS PAY and COMPUTE TAX), and others give incorrect results but results which are consistent with the data which they have had to operate on (e.g., COMPUTE NET PAY and, presumably, the printing of the pay details).
Without this display of intermediate results, the programmer would merely see that the final pay results produced were incorrect for the data input but would not know where the incorrect processing was occurring.
