Title: Problem with (princ) function
Post by: Lupo76 on June 30, 2016, 12:08:05 PM

I made a file that takes a long time to process.
So I decided to insert the following line of code:

(princ (strcat "\nObject " N " of "  TOT "."))

It works, but I do not see the text lines during the (while)process, but only at the end.
I feel that this happens because AutoCAD is too busy and therefore does not update the command bar.
Do you have any advice?

Can you post your section of routine?

If the princ is outside of the while loop, it will only display once the loop is exited.

If AutoCAD is rendered unresponsive by the OS as a result of the AutoLISP program/expression taking more than 5 seconds to evaluate, no output will be printed to the command-line until the program has completed evaluation. However, there are 'tricks' that one can use to ensure that AutoCAD is not marked as non-responsive by the OS, such as interspersing calls to the DELAY command or GRREAD function within the processing loop.

See this thread (https://www.theswamp.org/index.php?topic=50848.0) for more.
