And just to save others some time, "declaring code" is defined in this footnote: 'Every package consists of two types of source code— what the parties call (1)declaring code; and (2) implementing code. Declaring code is the expression that identifies the prewritten function and is sometimes referred to as the "declaration" or "header." As the district court explained, the "main point is that this header line of code introduces the method body and specifies very precisely the inputs, name and other functionality." Id. at 979-80. The expressions used by the programmer from the declaring code command the computer to execute the associated implementing code, which gives the computer the step-by-step instructions for carrying out the declared function.'
