I know I should probably experiment, but it would take quite a while to test all possible cases.
Can lists be passed as arguments? Can they be local vars only (i.e. nonglobal?) Are there any problems if a global list and a local list have the same name?
Thanks,
Ken
Can lists be passed as arguments?
You cannot pass a variable list to a [RoutineCall,…]. You should not approach zscripting that way. As only one Zscript can be active at a time and the variable definitions are cleared upon loading a new zscript, it makes sense to keep variables accessible throughout the active zscript.
Once defined, variable(s) in a zscript are accessible throughout the zscript, i.e global variables. However, if the variable definition is within a container the variable will first be accessible thoughout the zscript when that container has been activated. Your zscript logic will determine the variable(s) availability.
Variables defined at the root level are available immediately, throughout the zscript. You can think of the root level as a container that is activated once the zscript is loaded.
Are there any problems if a global list and a local list have the same name?
As variables in zscripts are global once defined you can only have one variable of a given name. [VarDef,…]'ing a variable name a second time will not cause any problems nor will it have any effect. A variables first [VarDef,…] is its final. You cannot extend a variable list by redifining it. To do that you need to use memory block commands.
