    Hi All,
       Consider the following "script.tcl":
            for {set x 0} {$x<10} {incr x}
            {
               puts "x is $x"
            }

      When on the TCL shell i say %source script.tcl
      The shell displays:
            wrong # args: should be "for start test next command"
      
      This is expected and correct.

    1. Now when i give the same as char * array to 'Tcl_EvalEx' function
    in my C program, 'Tcl_EvalEx' returns error '1'; which is also
    correct. But after this i want to display the same error string as
    displayed by shell. How to go about this ?

    2. I tried to get the error number thru 'Tcl_GetErrno' but whatever
    the type of error, 'Tcl_GetErrno' always returns 0. ny clues ??

    Thanks in Advance,
    Anand
