OBJ, ARRY, and LIST will be available in soft menu keys A, B,

and C. Function DROP is available by using „°@)STACK @DROP.

Following we introduce the operation of functions OBJ, LIST, ARRY, and

DROP with some examples.

Function OBJ

This function decomposes an object into its components. If the argument is a

list, function OBJ will list the list elements in the stack, with the number of

elements in stack level 1, for example: {1,2,3} ` „°@)TYPE! @OBJ@

results in:

When function OBJ is applied to a vector, it will list the elements of the

vector in the stack, with the number of elements in level 1: enclosed in braces

(a list). The following example illustrates this application: [1,2,3] `

„°@)TYPE! @OBJ@ results in:

If we now apply function OBJ once more, the list in stack level 1:, {3.}, will

be decomposed as follows:

Function LIST

This function is used to create a list given the elements of the list and the list

length or size. In RPN mode, the list size, say, n, should be placed in stack

level 1:. The elements of the list should be located in stack levels 2:, 3:, …,
