Hi Marc,

as concatenation, yes, but not as subscripting. The IDL reference guide
says:

Operator Precedence

The following table lists IDL's operator precedence. Operators with the
highest precedence are evaluated first. Operators with equal precedence
are evaluated from left to right.

Priority Operator

First (highest) ( ) (parentheses, to group expressions)
[ ] (brackets, to concatenate arrays)

Second . (structure field dereference)
[ ] (brackets, to subscript an array)
( ) (parentheses, used in a function call)

Third * (pointer dereference)
.
.
.

so my original question still holds.

regards,
lajos
