Why getvar is not working?

[Perifanos]

Can someone help me on why this code is throwing nil?

 

(command "_area")
 
 (while (> (getvar "cmdactive") 0) (command pause))
 
 (setq e (getvar "_area"))

 

e has nil value...

Try:

(command "_.area")
(while (> (getvar "cmdactive") 0) (command pause))
(setq e (getvar "area"))

I don't believe that getvar honors the "_"

Try :

 

(getvar "AREA")

Neither has worked !

(getvar "AREA") has worked.

 

Since when area should be written in capitals ????

ok, now why this is giving a "bad function"?

 

 (if (= fuel "a") ((setq kw (getreal)) 
		(setq p (* 6 kw))
		(setq a (* 0.25 k)))
  		      ((setq p (* 0.5 e))
	        (setq a (* 0.25 k)))
 
 )

Neither has worked !

 

You have certainly done something wrong.

(if (= fuel "a")
   (progn
       (setq kw (getreal)) 
       (setq p (* 6 kw))
       (setq a (* 0.25 k))  
   )
   (progn
       (setq p (* 0.5 e))
       (setq a (* 0.25 k)) 
   )
)

(if (= fuel "a")
  (setq kw (getreal "\nHow many Km?")
 p  (* 6 kw)
 a  (* 0.25 k)
  );; setq
  (setq kw (getreal "\nHow many Km?")
 p  (* 0.5 e)
 a  (* 0.25 k)
  );; setq
  );; if
;;or

(if (= fuel "a")
(progn
 (setq kw (getreal "\nHow many Km?"))
 (setq p (* 6 kw))
 (setq a (* 0.25 k))
);; progn
 (progn
   (setq kw (getreal "\nHow many Km?"))
   (setq p (* 0.5 e))
   (setq a (* 0.25 k))
 );; progn
);; if

 (if (= fuel "a") ((setq kw (getreal)) 
           (setq p (* 6 kw))
           (setq a (* 0.25 k)))
                ((setq p (* 0.5 e))
               (setq a (* 0.25 k)))
 
 )

 

Use progn

(if (= fuel "a")
 (progn
   (setq kw (getreal))
   (setq p (* 6 kw))
   (setq a (* 0.25 k))
 )
 (progn
   (setq p (* 0.5 e))
   (setq a (* 0.25 k))
 )
)

Or combine the grouped setqs

 

(if (= fuel "a")
 (setq kw (getreal)          p (* 6 kw)          a (* 0.25 k)  )
 (setq p (* 0.5 e)          a (* 0.25 k) )
)
