One of the most important ingredients of modular programs is keeping the same naming
conventions for variables. For example, in this book,
used to receive and manipulate stored information and sensor measurements. After
decisions are made based on
next subroutine. The same applies to the
loop in one subroutine, it is free to count in a different loop in the next subroutine.
In this activity, you will combine two programs that were developed in this chapter:
TestResetButton.bs2 from Activity #3, and PushbuttonMode.bs2 from Activity #5.
Because both programs follow the same rules for sectioning and temporary variable use,
they will be really easy to combine.
sections (I/O Definitions, Variables, EEPROM Data, Subroutines and so on). Both
programs also follow the same naming conventions for reusable variables like
counter
application programs building blocks for future programs.
Combining the Reset and Pushbutton Mode Programs
The first step to combining TestResetButton.bs2 and PushbuttonMode.bs2 is to save a
copy of one of the programs.
ResetAndStartMode.bs2. Then, we'll copy the elements from PushbuttonMode.bs2 that
were not already in TestResetButton.bs2. For example, TestResetButton.bs2 already had

reset-start function and the mode-select function.
