Something like %item but in data record
|
Hello!
I'm thinking about function, that will works like %item in string lists, but with data record variables.
Eg.
data = ogr=1|gnome=2|dwarf=3
etc etc.. let's say we have 100 position in variable data.
How to simply and fast take 3th position from @data ?
If it where a string list, I can make %item(@data,3). But this is data record. How to do it without loops? Any ideas? |

Nexela I has written that I want the 3th position in variable, and I don't know that 3th is dwarf
I dont want to use loop.
I want just something like %item(@data,3) but this wouldn't work with data record variable. |

| Code: |
| #VAR getN {%item(%expanddb(@data,|,|),%eval(%1*2))} |
#EVAL @getN(3) |
