I don't think a GO TO statement in COBOL monopolizes the CPU. A poorly designed program (with or without GO TO statements) can needlessly monopolizes the CPU. Typically GO TO statements can be avoided by having a good design. A local GO TO here and there is not so bad. The non-loc...
The root of it all is a paper "Go To Statement Considered Harmful" by E. Dijkstra; get Ed Yourdon's book "Classics in Software Engineering"; lots of classic papers in there, including this one. But the Go To in and of itself does not have a significant effect on CPU utilization. I ...

The first two steps are the same as those in the compile and link example (see related links). However, whereas in the other example we override the SYSLMOD DD statement in order to permanently save the load module, in Figure 1, we do not need to save it in order to execute it. ...
Dijkstra写了两篇现在很有名的论文,让这个问题更加明晰:Go to statement considered harmful, Notes on structured programming (PDF). goto:抽象破坏者 在这些论文中,Dijkstra担心的是如何编写有意义的软件并使其正确无误。我不能简单地加以评判,有太多迷人的见解了。例如,你可能看到过以下引用: 没错,这正是Notes...
(1)In a high-level programming language, a statement that directs the computer to go to some other part of the program. Low-level language equivalents are "branch" and "jump." (2)In dBASE, a command that directs the user to a specific record in the file. ...

Tape write mode is forced for the log in batch and GSAM data sets. In the sample IMSCOBGO procedure that is built during SMP/E processing and placed in the ADFSPROC and SDFSPROC library data sets, the IEFRDER2 DD statement is included as a comment. To use the IEFRDER2 DD statement,...
