* Some grid changing functions require that arguments are evaluated in
* an order other than the one in which they appear in the function call.
* For example, SAMPLEI(field, indices) requires that the "indices" argument
* be evaluated first, and then used to guide the process of obtaing "field"
* In this function we supply the re-ordered sequence for evaluation
