138 The Ultimate Palm Robot

The Break Component If you are inside a While or For component, Break
will stop executing the loop immediately and jump to the next component
following the For or While component. This component has no properties.

The Call Component Call allows you to call subroutines by name. After the
subroutine completes, control of the program passes to whatever component
comes after the Call. The properties of this component are the name of the
subroutine and a variable in which you can store any return value. If there is a
return value, you also need to add a Variable block to declare the variable. If
the subroutine does not return a value, the Variable field should be set to
empty. Also, you need to ensure if the Subroutine does return a value, that the
variable has the same type as the return value. We show you how to create a
subroutine in the section “Creating a Subroutine, Function, or Method,” later
in this chapter.

The Include Component This block allows you to include another source
file into the program. This is provided for TEA and Java programs. TEA
allows you to include other source files into a TEA program and call the
subroutines in the other source file by name. The property for this component
is the name of the source file. For example, if you install the BrainStem
software, you will have a directory named \aSystem. This directory contains
source code files that you can include. One such source file is aPPRK.tea. If
you add an Include block and set the filename property to aPPRK.tea, the
source file created for your program will have a statement to include the
aPPRK.tea file and you can use aPPRK.tea functions in your program.
