SIZE

Type: Command Operation

Description: Size Command: Returns the number of characters in a string, the number of digits in an integer, the number of elements in a list, the dimensions of an array, the number of objects in a unit object or algebraic object, or the dimensions of a graphics object.

The size of a unit is computed as follows: the scalar (+1), the underscore (+1), each unit name (+1), operator or exponent (+1), and each prefix (+2).

Any object type not listed above returns a value of 1.

Access: !°LCHARS SIZE

( °is the left-shift of the Nkey).
