Tuple Value Expressions

<set>.CURRENTMEMBER

Gives the current tuple in set. The concept of “currency” occurs in functions such as GENERATE where the semantics include some form of iteration through tuples of a set.

<set>[.ITEM](<string_expression> [, <string_expression>...] | <index>)

Returns a tuple from set. The <string_expression> [, <string_expression>...] specifies which tuple to retrieve. The index value specifies the position of the tuple in set. The numbering of the tuples is zero-based.
