Compatibility: Expression-List as Array-Initialization

[riederm]

There is existing code that uses an Expression-list as an array-initialization and I think we should be compatibilt to this.

	FACTS : ARRAY[0..12] OF DINT := 1,1,2,6,24,120,720,5040,40320,362880,3628800,39916800,479001600;

this code is from oscat basic library.
