Debug program

We have also set up a software library on the 32-bit minicomputer that allows us simulate the diffractometer operation as an aid to developing and debugging programs offline. 

The barriers to integration identified earlier in Sections 2.5 and 3.2 will influence the selection of the pilot location. Resistance is often very high for pilot studies—most managers would rather have someone else debug a new program before they have to work with it. This resistance is even more...

Advice on Debugging and Verifying Computer Programs. The computer programs needed so far have been relatively simple. Most of the problems can... 

Long programs will take hours and even days to write and test. A systematic approach to debugging and verification will reduce this time to a minimum. It will also give you confidence that the numbers are right when they finally are produced. 

The number of radial increments can be picked arbitrarily. A good approach is to begin with a small number, /= 4, for debugging purposes. When the program is debugged, the value for / is successively doubled until a reasonable degree of accuracy is achieved or until computational times become excessive. If the latter occurs first, find a more sophisticated solution method or a faster computer. 

Systematic verification is needed for a program as complex as this. The following tests were made using Itotal = 32. A sequence like this helps in debugging and lends confidence to the final results, although they do not prove...

Eiffel is among the few programming languages to provide directly for operation specs, but they can, of course, be documented with an operation in any language. In C++, suitable macros can be used Java could use methods introduced on the superclass Object. For debugging, pre- and postconditions can be executed. 

Therefore my recommended technique is to start with a very small step size to get the program debugged and running. Then make a few quick empirical tests in which you keep doubling the step size. Check the accuracy of successive runs and continue increasing the step size until you find the biggest At that gives sufficiently accurate answers and is stable. 

B1 - B2 These cells contain the values of the variable names in cells A1-A2. The association of the numbers in B1-B2 with the names in A1-A2 is accomplished with the INSERTJMAMEJDEFINE command. (The syntax INSERT NAMEJDEFINE means to use the INSERT pull-down menu, followed by the DEFINE and NAME sub-menus. In many cases there are also convenient keyboard shortcuts that avoid actually using the pull-down menu.) As much as possible, it is important to define names that appear in subsequent formulas. It is very difficult to read and debug a spreadsheet that is programmed entirely with explicit cell references. The variable name for the annulus gap thickness Delta r is in A3 and the value is computed in B3 as = r.out - r in.
