As with all professional programming tasks, careful planning will save development time. When building a ToolBook application, keep the following considerations in mind:
A ToolBook application's performance is a function of the type and number of objects are used. ToolBook's objects are displayed as discrete vector graphics that can be easily moved and edited. Windows, however, does not display vector graphics objects as quickly as it displays bitmaps, which are not as easily edited.
ToolBook does not compile books into .EXE files, although OpenScript scripts compile into pCodes, which are executed at runtime.
Calling DLLs from OpenScript may challenge inexperienced programmers. A basic understanding of C-style functions, their declarations, and their usage is helpful.
Because you cannot examine link structures or update data or links globally in ToolBook, updating typically must be done on a page-by-page basis.
