Depth

SUMMARY

Depth - The number of elements is pushed onto the stack.

SYNTAX

Depth();

DESCRIPTION

1. The number of elements is pushed onto the stack.

Returns the number of elements on the stack. Since the result is pushed to the stack too, the number of stack elements is by 1 higher than the returned value.

EXAMPLES

//Stack before (4 Elements):
//"a"
//"b"
//"c"
//"d"
Depth();
//Stack afterwards (5 Elements):
//4
//"a"
//"b"
//"c"
//"d"
