variable value in getdist function

Hi,

I am trying something very simple, but I am out of ideas already

(setq interval 5)

(setq dist (getdist "\nEnter Interval :"))

Hi Chavdar,

if you mean the interval value in the prompt, perhaps something like this

(setq interval 5) 
(setq dist (getdist (strcat "\nEnter Interval < " (itoa interval)" >:")))

EDIT: If your goal is to force the user to enter a number divisible by 5, maybe something like this

(setq interval 5)
(while (not
        (progn
          (initget 7)
          (setq dist (getreal (strcat "\nEnter Interval < " (itoa interval) " >:")))
          (= (fix (/ dist 5)) (/ dist 5))
        )
      )
)

To check for divisibility, you could also use:

(zerop (rem dist 5))

To check for divisibility, you could also use:

(zerop (rem dist 5))

More concise.

Thank you Lee!

No worries!

what is it means by rem dist ?

what is it means by rem dist ?

The expression returns the remainder when dividing the numerical value held by the variable 'dist' by 5.
