VERY confused about forking of child process

hi, I thought that when a child shell is forked, it will inherit all the variables of the parent now in my .cshrc I have setenv X x then I do at command line setenv X y and X is now y. So far so good! I then have a very simple script, y.csh #!/usr/bin/csh echo X

NAME

       jstack - stack trace

SYNOPSIS

       jstack [ option ] pid
       jstack [ option ] executable core
       jstack [ option ] [server-id@]remote-hostname-or-IP

DESCRIPTION

       jstack  prints  Java  stack traces of Java threads for a given Java process or core file or a remote debug server. For each Java frame, the
       full class name, method name, 'bci' (byte code index) and line number, if available, are printed. With the -m option,  jstack  prints  both
       Java  and  native frames of all threads along with the 'pc' (program counter). For each native frame, the closest native symbol to 'pc', if
       available, is printed. C++ mangled names are not demangled. To demangle C++ names, the output of this command may be piped to c++filt.

       NOTE - This utility is unsupported and may or may not be available in future versions of the J2SE SDK.  jstack is not  currently  available
       on Windows platforms or on the Linux Itanium platform.

PARAMETERS

       Options are mutually exclusive. Option, if used, should follow immediately after the command name.

       pid	      process  id  for which the stacktrace is to be printed.  The process must be a Java process. To get a list of Java processes
		      running on a machine, jps may be used.

       executable     Java executable from which the core dump was produced.

       core	      core file for which the stack trace is to be printed.

       remote-hostname-or-IP
		      remote debug server's (see jsadebugd) hostname or IP address.

       server-id      optional unique id, if multiple debug servers are running on the same remote host.

OPTIONS

       -m	      prints mixed mode (both Java and native C/C++ frames) stack trace.

       -h	      Prints a help message.

       -help	      Prints a help message.

SEE ALSO

       pstack(1) c++filt(1) jps(1) jsadebugd(1)

KNOWN BUGS

       Mixed mode stack trace, the -m option, does not work with the remote debug server.
