3.8 Constant Operand Tokens
3.8.7 tArray (20 H , 40 H , 60 H )
This token contains an array constant. For instance the 2x1 matrix {1;2} is an array constant. The values of the array
constant do not follow the token identifier but are stored behind the complete token array (➜3.1.6) in a constant value
array(➜2.5.8). This token is not allowed in conditions of conditional formattings and in data validity. If this token is
used in cell formulas, it prevents the creation of shared formulas. Operand class: array.
