index
Description
Recovers an object from a lower level of the operand stack.
Usage
NAny..0Any IndexInt index NAny..0Any IndexedAny
NAny..0Any Any. All objects on the operand stack.
IndexInt Integer. Index of desired object on operand stack. The top-most object, prior to
pushing IndexInt, has an index of zero. The next lower object has an index of
one.
IndexedAny Any. Requested object from operand stack.
Comments
This operator functions in a manner similar to the dup operator. However, index duplicates any
object on the operand stack. For composite objects, the original and duplicate objects will share
the same composite data.
