problem passing arguments to script
Hi,
I am writing a script, which is invoked from other system using ssh.
I have problems reading the arguments passing to the script. If the argument has a space in it (ex "rev 2.00"), the script considers "rev" as 1 argument and "2.00" as another. Instead i want "rev 2.00" to be considered as a single argument.

Below is my script and sample output.

Code:
#myscript.sh

#! /bin/bash
     script=${0##*/}
     value1=$1
     value2=$2
     value3=$3

     echo "received parameters :"
     echo "script: $script, value1: $value1, value2: $value2 value3: $value3"

Output:
bash-3.00$ ssh root@192.168.10.121 /usr/local/sbin/myscript "Rev_1" "Rev 2" "Rev3"
root@192.168.10.121's password:
received parameters :
script: myscript, value1: Rev_1, value2: Rev value3: 2

desired output:
script: myscript, value1: Rev_1, value2: Rev 2, value3: Rev3

tcl_allowexceptions

Tcl_AllowExceptions(3)					      Tcl Library Procedures					    Tcl_AllowExceptions(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_AllowExceptions - allow all exceptions in next script evaluation

SYNOPSIS

       #include <tcl.h>

       Tcl_AllowExceptions(interp)

ARGUMENTS

       Tcl_Interp *interp (in)		Interpreter in which script will be evaluated.
_________________________________________________________________

DESCRIPTION

       If  a  script is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is invoked), and if the script termi-
       nates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN, then Tcl normally converts this into a TCL_ERROR  return  with	an
       appropriate  message.  The particular script evaluation procedures of Tcl that act in the manner are Tcl_EvalObjEx, Tcl_EvalObjv, Tcl_Eval,
       Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA.

       However, if Tcl_AllowExceptions is invoked immediately before calling one of those a procedures, then arbitrary completion codes  are  per-
       mitted from the script, and they are returned without modification.  This is useful in cases where the caller can deal with exceptions such
       as TCL_BREAK or TCL_CONTINUE in a meaningful way.

KEYWORDS

       continue, break, exception, interpreter
