Example of a formula involving a complicated function

This example uses a function which takes two arguments and returns an array of results, which are identified by name. In the formula, the return value named VAL1 is being retrieved.

y*MyFunc(z,3:VAL1)

Written as an unparsed formula, each token is directly transcribed as follows:

Written as a parsed formula (in reverse Polish), an evaluation order is established first, for example:

y  )  VAL1  :  3  ,  z  MyFunc(  *

and this is then transcribed as follows:

Notice that the function arguments are in reverse order, including the name of the return value and the colon delimiter, and that a right bracket is used as a delimiter to indicate the end of the argument list.
