#2 Format display of symbols required

[Anonymous]

A way to control the display of some functions.

For example in order to show a Tensor we need a symbol
with many up and sub indexes.

This could be expressed like:

Format[ Tensor[A_,sub_,sup_] ]:=
Subsuperscript[A,sub , sup ];

and would display for example:

Tensor[A,i,j]

-------------
i
A
j
