Figure 13-15. Unless you say otherwise, all custom functions appear in the functions list of each
Specify Calculation window. Here the list is arranged as “all functions by type.” You can see the
several custom functions from Figure 13-14 listed in alphabetical order. Just above them are func-
tions specific to FileMaker Go.
NOTE
You may not actually need to calculate circumferences in your own databases much, but this ex-
ample shows important concepts common to creating any custom function. Plus, it's easier to type
than most real-world examples. See this chapter's sample file,
Dev Tools.fmp12
