trying to do a lisp routine- help

I want to make a quick lisp routine that will take the cubic inches from a
massprop command and calculate weight (lbs and kgs) from that. Anyone have
a quick solution? Thanks.

 

Show us the code you've got so far.

 

LISP ROUTINE IS:

(defun c:conv (/ input1 matx output)

(setq dcl_id (load_dialog "conv1"))

(new_dialog "conv1" dcl_id)



(action_tile "cubin" "(do_cubin)")

(action_tile "accept" "(done_dialog)")

(action_tile "cancel" "(done_dialog) (cuberr)")





(defun do_cubin ()

(setq cubin1 (get_tile "cubin"))

)

(start_dialog)



(setq output (* do_cubin 0.28355))

(unload_dialog dcl_id)

(princ "\nWeight in pounds is : " output)

)



DIALOG BOX IS:

dcl_settings : default_dcl_settings {audit_level = 0;}

conv1 : dialog

{

label = " converter";

width = 40;

spacer_1;

: text {

label = " Enter the cubic centimeters: ";

width = 40;

}

: boxed_column

{

fixed_width = true;

width = 17;

alignment = centered;

: edit_box {

label = "cubic-centimeters:";

key = "spout";

mnemonic = "D";

edit_width = 5;

}

}

spacer_1;

: text {

label = " Once your entry is made, select the OK";

}

: row {

width = 20;

alignement = centered;

spacer_0;

: ok_button {

label = "-OK-";

key = "accept";

fixed_width = true;

width = 8;

alignment = centered;

}

: cancel_button {

label = "CANCEL";

key = "cancel";

fixed_width = true;

width = 8;

alignment = centered;

}

spacer_0;

}

}

 

nevermind. all set. here is the code I ended up with:

(defun c:qw ()

cmdech (getvar "CMDECHO")

(setvar "CMDECHO" 0) ;turn echo off

(setq out1 0)

(setq outk 0)

(setq ptX 0)

(setq output 0)

(setq outk 0)



(setq thefile "tempx.mpr")

(command "massprop" pause "" "y" thefile)

(setq afile (open "tempx.mpr" "r"))


(setq cpt 1)

(while (setq aline (read-line afile))

(if (= (substr aline 1 4) "Mass")

(progn

(setq ismass 1)

(setq avalue 1)

(setq ptX (atof (substr aline 26)))

) ;progn

); if

)

(close afile)

(command "del" "tempx.mpr")



(setq out1 (+ 0.28355))

(setq outk (+ 0.4536))

(setq output (* out1 ptX))

(setq outputk (* output outk))

(setq wt1 (rtos (* out1 ptX)))

(setq wt2 (rtos (* output outk)))

(setvar "CMDECHO" 1) ;turn echo on



(princ "weight in pounds: ")

(princ output)

(princ " weight in kgs: ")

(princ outputk)

(princ)

)
