Syntax Problems with map() and apply()

[mark4flies]

I want to use the map() or apply() function to stream over a list or vector but I keep getting a syntax error, even when I enter the example from the User Guide or Help! Here is the first example from Help for apply():

apply( x->x^3, [1 2 3] )

results in a syntax error message. The cursor is left after the first occurrence of x.

I use these functions in other languages all the time. I kind of think of solutions in terms of them - very useful! Please help me how to properly call them in HP PPL.

Thanks!
