I compiled the xchem from scratch, when I try to output variable using put command, the xschem will sometimes exit. The error message is like below. Should I go to github to report this type of issue?

the syntax is

puts $variable

do not issue commands if some dialog boxes are open. the message above is issued by tclreadline hen giving commands when xschem is processing some user action, like an open dialog box. If you still get these problems start xschem without tclreadline (

xschem -r

)
