[amibroker] Re: A shorter syntax to reference past elements of array

["markhoff" <markhoff@xxxxxx>]

Tomasz, just one question: is the bar shift limited to fixed numbers
or will it also be possible to use variables or expressions, e.g.:

a) c@x
b) c@x+k
c) c@(i+k)

Will the parenthesis be required for expressions?

Regards,
Markus
