Question

This is my function:

(defun MyFunction(input)
  (let ((NEWNUM (find input num)))
    (if (find input num)              //if this 
      (setq num NEWNUM) (FUNCT2)      //then execute both of these
    (list 'not found))))              //else output this

So after the if statement I want to be able to execute (setq num NEWNUM) followed by (FUNCT2) in order to set a new variable and then call a function. Any ideas on how to do this?

Answer 1

To do several things in sequence, you want progn.

(defun MyFunction(input)
  (let ((NEWNUM (find input num)))
    (if (find input num)              //if this 
      (progn 
        (setq num NEWNUM)
        (FUNCT2))      //then execute both of these
    (list 'not found))))              //else output this
