I suppose there is no progn

[shercipher]

For expressions that need to be evaluated sequentially in newLisp, there is no progn special form that says "evaluate these and return the last".

So how do I make code like this valid?

Code: Select all

(if (expr)
 ((eval 1) (eval 2) (eval3))
 (eval4))

It seems to execute the forms correctly, except that at the end of executing the forms it says "ERR: value expected: (whatever the last form was)"

Use 'begin' instead.

Or somewhere:

Code: Select all

(setq progn begin)
(constant(global 'progn))

Then you have 'progn'
