1. If there is no field inside Record Token, it will add it into Record Token

   Code Block
   { a = 1 } -> inputRecord -+ | >- { a = 1, b = 2 } | 2 -> b -+ // I am passing value 2 into port with the name b - new  // entry inside record will be created

2. If there is a field with given name inside Record Token, it will be replaced
   
   

   Code Block
   { a = 1, b = 1 } -> inputRecord -+ | >- { a = 1, b = 2 } | 2 -> b -+ // I am passing value 2 into port with the name b - old  // value will be replaced with new one

3. If there is a field with given name inside Record Token, the type of field may change if you pass different type in the input

    

   Code Block
   { a = 1, b = 1 } -> inputRecord -+ | >- { a = 1, b = { c = 2 } } | { c = 2 } -> b -+ // I am passing record { c = 2 } into port b - old value  // will be replaced with Record Token element (nested Record Token)

4. You can modify nested Record Type values by separating names of elements with /. E.g. you can specify "a/b"
   
   

   Code Block
   { a = { b = 1} } -> inputRecord -+ | >- { a = 1,{ b = { c = 2 } } | 2 -> a/b -+ // I am passing value 2 into port a/b - this time, I modify element a.b inside Record Token // note that we have to use "/" in port name due to the fact Kepler  // doesn't allow to use "." as name separator

1. Getting single value from recordget can be done by specifying element's name as output port
   
   

   Code Block
   +- // -> { a = 1, b = 1 } // you can always get original record via "//" port | { a = 1, b = 2 } -> inputRecord -+ | +- b -> 2 // we get value of element "b"

2. Getting multiple values can be done by specifying multiple names
   
   

   Code Block
   +- // -> { a = 1, b = 1 } // you can always get original record via "//" port | { a = 1, b = 2 } -> inputRecord -+- a -> 1 // this time, we get also value of element "a" | +- b -> 2 // we get value of element "b"

3. You can use nested names to get values from the nested parts of Record Token
   
   

   Code Block
   +- // -> { a = 1, b = { c = 3 } } // you can always get original record via "//" port | { a = 1, b = { c = 3 } } -> inputRecord -+- a -> 1 // this time, we get also value of element "a" | +- b -> { c = 3 } // this time, we get a record from b | +- b/c -> 3 // and here, we are accessing element b.c by specifying full path // to nested element

In Kepler you have two ways of generating Record Token. You can use either Record Assembler (with empty input) or Constant actor with "emptyRecord()" value inside
