I use the following line to sent several drawings to our copier: (dos_command (strcat "copy /b c:\\hcad\\tmp\\OceHeader.ini+\"" bnm "\" \\\\he-filesrv\\OCE9600R > c:\\hcad\\tmp\\result9600.txt") 3) But when i use this to sent a list of drawings through lisp, it will not work beceause one after the other are being sent to fast and then get into conflict with each other. There has to be a delay, but the delay depends on the size of the plotfile. Is there a way to 'after sending the plotfile, interrupt the lisp-process untill the plotfile is sent, and then 'after that, proceed with sending the next plotfile so that they won't get into conflict with each other. I hope i'm clear on the subject. I thought dos_exewait was the solution but this does not seem to be suitable for dos commands. Regards MJ
