| how to use delete each? Thanks. |

Type thing Field blah End Type Delete Each thing |
| ||
| Type Monster Field Name$ Field X, Y End Type ThisMonster.Monster = New Monster ThisMonster\Name$ = "Bartholemew" ThisMonster.Monster = New Monster ThisMonster\Name$ = "Humperdink" For ThisMonster.Monster = Each Monster Print ThisMonster\Name$ Next Output: Bartholemew Humperdink Delete Each Monster For ThisMonster.Monster = Each Monster Print ThisMonster\Name$ Next Output: (Nothing) "Delete Each" simply deletes all copies of a type you have created with New. In fact, Delete Each isn't actually a command, it is two commands. The main command is Delete. The word Each is a modifier telling Delete what to delete. So you can: Delete First Monster or Delete Last Monster or Delete Each Monster or Delete ThisMonster |

You can even do this:Type thing Field x,y End Type For f = 0 To 10 th.thing = New thing th\x = f Next Delete After First thing Delete Before Last thing For th.thing = Each thing Print th\x Next Stop End ie. After First and Before Last. |
