The procedures in this library provide some convenient tools for working with lists of Key,Value pairs.

Create a global variable and set it's value to the empty list to hold your list of pairs.

Then you can use any of the following procedures to manage the list:

CreatePair(Pairs,Key,Value) - create a Key,Value pair
RemovePair(Pairs,Key) - remove a Key,Value pair
SetValue(Pairs,Key,Value) - set the Value associated with Key (pair must exist)
GetPairIndex(Pairs,Key) - returns the index of the pair
GetKeys(Pairs) - returns a list of Keys
GetValue(Pairs,Key) - returns the Value associated with a Key

Copy these procedure blocks to Backpack for use in your projects.

The Examples file contains example uses of each of the procedures.

Could you add these to the Gallery too?

I have trouble getting to the Developers library.
