NAME

       exit - End the application

SYNOPSIS

       exit ?returnCode?
_________________________________________________________________

DESCRIPTION

       Terminate the process, returning returnCode to the system as the exit status.  If returnCode isn't specified then it defaults to 0.

EXAMPLE

       Since  non-zero	exit  codes  are  usually interpreted as error cases by the calling process, the exit command is an important part of sig-
       nalling that something fatal has gone wrong.  This code fragment is useful in scripts to act as a general problem trap:
	      proc main {} {
		  # ... put the real main code in here ...
	      }

	      if {[catch {main} msg]} {
		  puts stderr "unexpected script error: $msg"
		  if {[info exist env(DEBUG)]} {
		      puts stderr "---- BEGIN TRACE ----"
		      puts stderr $errorInfo
		      puts stderr "---- END TRACE ----"
		  }

		  # Reserve code 1 for "expected" error exits...
		  exit 2
	      }
