- Is formatting done primarily to illuminate the logical structure of the code?
- Can the formatting scheme be used consistently?
- Does the formatting scheme result in code that's easy to maintain?
- Does the formatting scheme improve code readability?
- Does the code avoid doubly indenting begin/end pairs?
- Are sequential blocks separated with blank lines?
- Are complicated boolean expressions formatted for readability?
- Are single-statement blocks formatted consistently?
- Are case statements formatted in a way that's consistent with the formatting of other control structures?
- Have gotos been formatted in a way that makes their use obvious?
- Do incomplete statements end the line in a way that's obviously incorrect?
- Are continuation lines indented sensibly?
- Are groups of related statements aligned?
- Are groups of unrelated statements unaligned?
- Does each line contain—at most—one statement?
- Is each statement written without side effects?
- Are data declarations aligned?
- Is there--at most--one data declaration per line?
- Are the comments indented the same as the code?
- Is the commenting style easy to maintain?
- Are the arguments to each routine formatted so that each argument is easy to read, modify, and comment?
- In C, are new-style routine declarations used?
- In Fortran, are parameters declared separately from local variables?
Files, Modules, and Programs
- Does each file hold code for one and only one module?
- Are routines within a file clearly separated with blank lines?
- If a file does contain multiple modules, are all the routines in each module grouped together and is the module clearly identified?
- Alternatively, are all routines in alphabetical sequence?
