Labels

Labels mark a location in the code. They can be used by certain commands to perform unconditional (jump, gosub) or conditional (goto_if_false) transfer of control flow to the marked location.

To create a new label in the code use : followed by a valid identifier (a label name).

:MyLabel

To reference this label in a command, use @ followed by the label name.

jump @MyLabel

If a label name is written as a standalone statement followed by (), it represents a gosub command (a subroutine call):

// the following statements are equivalent
MyLabel()
gosub @MyLabel
