This tip only works for ND6.
You may use this function extensively to eliminate the hard coding of field names. It is especially useful when you have a lot of fields. and each time you have to write the field name in several sections of the field design areas.
In addition, you may write your codes as a context, so that you may use it whenever you need it regardless of the need to re-assign the field name.
For example, you may use it to trim the value in the input translation section like (@Trim(@GetField(@ThisName)) or, for a multi-value field, @Unique((@Trim(@GetField(@ThisName))).
You may also use it in the def value and validation sections and a lot of aspects of field value processing.
Note: In this context I tested the function (@GetField) in a multi-value field and I found it working well, but not as documented (that is, it returns only the first value).
