[3.30] Helpfile: %isvalue and %item
|
The help file for %isvalue states:
| Quote: |
It actually returns the position of the value in the database record for use with %item to retrieve the key.
#SHOW %item(@dbvar, %isvalue(@dbvar,"Dwarf"))
Displays: Race=Dwarf |
This is not the case. It only shows the value again or Dwarf and not the key. |

That should be changed to state you can use %dbkey with it to retrieve the key?
| Code: |
#SHOW %dbkey(@dbvar, %isvalue(@dbvar,"Dwarf"))
Displays: Race |

I'm not sure if the help files have been updated, but the example posted works fine for me. The only discrepancy is the output is
vs the output in the help file, i.e.
| Code: |
Displays: 2
Displays: Race=Dwarf |

Yes but according to to the help file it says "It actually returns the position of the value in the database record for use with %item to retrieve the key." You can't retrieve the key with %item.

The help file is old. Hopefully it will be updated, but that's the only problem. %dbkey, as you mentioned, is the new replacement for that and using %isvalue with %dbkey works just fine. You could also just make a comment in the helpfile ;)

I've gone ahead and updated the documentation.
