Before you can execute a script, you must compile it.
To compile a script:
Click the Compile button, or select Edit>Compile from the menu bar.
PocketBuilder compiles the script and reports any problems it finds, as described in “Handling problems”.
PocketBuilder compiles automatically
When you attempt to open a different script in a Script view,
PocketBuilder compiles the current script. When you save the object,
such as the window containing a control you wrote a script for,
PocketBuilder recompiles all scripts in the object to make sure
they are still valid. For example, PocketBuilder checks that all
objects that were referenced when you wrote the script still exist.
