Description

If the Return statement will not resume the operation in the original subroutine, use the Goto function.
If the specified label does not exist for a parameter, an "Undefined label" error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
