Overview
| Comment: | Implement (attribute userflags) syntax, in order to access bit patterns of user flags directly in class codes (e.g. so that they can be passed to subroutines, etc). |

(Put the colon after the equal sign; this instruction, and the one below, are using a double sigil.) ,<label> Call a label as a subroutine; when it returns, comes back to here. (<attribute> <userflags...>) ( -- number ) The attribute must be one of Misc4, Misc5, Misc6, Misc7, or CollisionLayers, and may optionally be preceded by a comma. This produces the number with all of the specified bits set only. If the attribute is preceded by a comma, then it is an error to specify any user flags not assigned to that variable, otherwise any user flags that do not belong are ignored. Any user flag may optionally be preceded by a comma, and may occur multiple times; only the last instance of each is used. If the last instance of a flag has a comma then that bit is clear, if without a comma then it is set. . ( x -- ) + ( in1 in2 -- out ) Add two numbers together. - ( in1 in2 -- out ) Subtract in2 from in1. |
