Hi,
Have created an expression rule "increment" with one rule input "x", has the following definition :
with(
ri!x:ri!x + 1,
ri!x
)
I call this rule from another expression rule ::
with(
local!a:rule!increment(x:ri!y),
local!a
)
returns 11 if value of ri!y is 10, works fine.
But if I use the following code:
with(
local!a:rule!increment(x:ri!y),
ri!y
)
returns 10 if value of ri!y is 10.
I have two queries here :
1. Are rule inputs to expression rules Passed By Reference or Value ?
2. How can I design a rule which can return multiple values ?

Answer for question 1:
As per documentation, Rule inputs are used to pass data into the expression rule. (Pass by variable) approach.
To answer your 2nd question,
If you want to apply same logic for multiple inputs use apply function which will return any type array.
Otherwise, use {} and define the logic in side {}.
