(quote T) ?

i found shortest expression is (and)
(= t)

[JohnK]

Thinking:
(t)
(eval t)
(and t)

Thinking:
(t)
(eval t)
(and t)

(and)   not need t

(t) is wrong,   t is not a function

[Marc'Antonio Alessi]

Code: [Select]

_$ T

_$ (T)
; errore: funzione errata: T
_$ (
_$ (and T)

_$ (and)
T
_$ (eval T)
T

baitang36,

...or you could just create your own short expression which will return T?

Code - Auto/Visual Lisp: [Select]

1. (defun : () t)
2. .....
3. Command: (:)
4. T
5.  

Best,

Nice.

Also in that spirt (not as short but much the same--result wise).
(set ': (lambda nil T))
