Stack

Stack	Position	Description

Each value on the stack can be assigned to a variable. The sequence -> variableName is to be understood as a single instruction; -> wants to be understood as a symbol for assignment (see example).

Stack

Stack	Position	Description
Stack(In)	Top	]
	Top 1	Value n
	. . .	. . .
	Top-n	value 1
	Top n-1	[
Stack(Out)		-

A vector can also be assigned to a variable.

Assignments within a transaction are cancelled when the transaction is aborted due to an error or a cancel statement (the variable is returned to the value it had before the transaction started).
