Topic: AutoLISP - Pausing code during LISP-routine execution

[markyspark]

--------------------------------------------------------------------------------
I'm looking for a command that pauses the execution of code during a routine, but not using the break function in the debugger. I seem to remember reading somewhere (Where??) that there IS a command, such as (pause 1000) where the argument is a integer denoting the milliseconds to pause the code execution. Anyone know anything about this? Help?

"WAIT" I believe

I believe that's a script command, e.g. PAUSE 1000. AFAIK, here is no such function in AutoLISP.

But you can write one:

Code: [Select]

(defun pausing (msecs / tmp)
  (setq tmp (+ msecs (getvar "MILLISECS")))
  (while (< (getvar "MILLISECS") tmp)))

It's not 100% accurate as GETVAR takes the time it needs but it's close. NB: don't rename it to "pause" or you'll overwrite the PAUSE constant.

Try this one.  I used it somewhere at some time?

(defun wait (seconds / stop)

  (setq stop (+ (getvar "DATE") (/ seconds 86400.0)))
  (while (> stop (getvar "DATE"))
    (princ)
  )
)

(command ".delay" "1000"); = pause 1000 miliseconds

I started with the delay command but for some reason it was't very reliable.  That was the reason for the alternative.

Thanks a bunch...haven't tried the ideas but based on past experience I am sure they'll all work. I didn't even think about using the internal clock!

By the way Mr. Madsen...what does AFAIK stand for?
