uChoice

Returns the value of a given parameter specified by an index. The index value is zero-based, so an index of zero returns the second parameter.

Syntax

string uChoice(index, values, ...)

Example 1 – IF construct:

uChoice(0, "A", "B") // returns "A"

uChoice(1, "A", "B") // returns "B"

CASE construct:

uChoice(2, "n.a.", "Jan", "Feb", "Mar") //returns "Feb"

Simulate a lookup function, where you want to replace a color ID with a corresponding color name:

 uChoice(IN.Color, "n.a.", "Red", "Blue", "Green")
