Limit String List
|
Hi,
I got a string variable which has like 50 items...
Is there a comand to delete items from 31 - 50?
I just need the first 30 variables.

Here's a method I use... rather ugly tho:
| Code: |
#var temp ""
#loop {1,30} {%additem(%pop(YOUR_LIST),@temp)}
#var YOUR_LIST ""
#loop {1,30} {%additem(%pop(temp),@YOUR_LIST);
#unvar temp

Assuming the items are unique you can use:
#VAR List {%left(@List,%eval(%pos(%item(@List,30),@List)+%len(%item(@List,30))))}
If they are not:
#WHILE (%numitems(@List)>30) {#DELNITEM List 31} |

Hi,
This is what I do for the string variable actually.
This is basically a alias which I run to output the room number which matches a room name input. However some common names generate hundreds of variables.
#VAR QueryRoom %MAPQUERY( Name LIKE ~'~%%1~%~')
Can we limit the list to 30? |

Via SQL, you can. That's outside of the zscript scope, though, so it's up to the SQL gurus to say how to do it.
