select varname in opt1 opt2...optN
do
case $varname in
opt1) command1;;
opt2) command2;;
optN) commandN;;
esac
done
Looking at this skeleton for a select statement, I am baffled as to what exactly "in" does. Does it pass a reference off from the first variable to the second?
I apologize for such a beginner question.

__________________________________________________________________________________________________________________________________________________NAME
observe - Runtime debugging output in TkCon
SYNOPSIS
observe command cmdname ?maxlevel?
observe cdelete cmdname
observe cinfo cmdname
observe variable varname operation ?args?
observe vdelete varname operation
observe vinfo varname
_________________________________________________________________DESCRIPTION
This command provides runtime debugging output for variables and commands without the need to edit your code. For variables, the underly-
ing mechanism uses trace and dump var. For commands, it renames the observed procedure and uses a special wrapper procedure. WARNING:
using this procedure after checkpointing state will result in major problems if you clean state because the renamed (true) commands will be
lost.
This procedure is experimental. Comments are encouraged.
observe command cmdname ?maxlevel?
This will create a wrapper command which prints out (using dump) the call stack to the console. maxlevel represents the maximum
number of levels of the call stack which will be printed (defaults to 4).
observe cdelete cmdname
Removes the wrapper around an observed command.
observe cinfo cmdname
Prints out useless info.
observe variable varname operation ?args?
Currently a wrapper around trace that uses dump to print out the value of the named variable whenever the specified operation on
that variable occurs (must be read, write or unset).
observe vdelete varname operation
Deletes the trace wrapper around the named variable.
observe vinfo varname
Prints out trace info about the named variable.
