Example Error Message

Lexical error at line 1:

IndexLength( ['a', 'b', 'c' ] )

             ↑

Expected an index identifier for «I», the first parameter of IndexLength.

Description

The parameter expects an index identifier. This can be a single identifier such as Month, or it can be a local index syntax such as Projections.Month. In the above example it is neither -- it is a list. For that case, the function Size could be used instead.
