Look at the help for COPY.
? copy
There you can see:
/part -- Limits to a given length or position.
range -- (Type: number series port pair)
When you use INDEX?, you get a number, and COPY uses that as a length.
When you use a series directly, COPY uses its index to specify the position
of the end of the copy.
In other words:
- A number specifies a length, so the end position is always relative to the
start position.
- A series specifies an absolute ending position.
