MicroScript Error Messages

The following two types of error messages are issued by MicroScript:

Error messages that appear when reading a script (compiling to intermediate language)
Error messages that appear when a script is is executed (when the MicroScript engine executes the intermediate language)

We will respectively explain the messages that are displayed and their causes. Please make use of them in debugging programs.
