Taking into account the earlier postings and error messages you will have seen during testing, by now your shell script should look something vaguely like this example:

Code:
#!/bin/ksh
counter=0
sales=0
total=0
while [ "$sales""X" != "X" ]
do
     echo "Enter sales price: \c" ; read sales
     let counter=$counter+1
     let total=$total+$sales
     echo "Counter : $counter"
     echo "Running total: $total"
done


The first line (the shebang line) states which shell we are using.

Indentation adds to readability.

We have appended an arbitary character "X" to "$sales" in the while statement to avoid the syntax error when we finally don't enter a value and want to exit the loop. (There are other ways of achieving the same effect).

For completeness and readablility we initialise $total .

We can extend the "echo" statements to improve the layout on the screen and to provide more information about what the output means. The "\c" in the first echo stops echo outputting a newline character such that the user enters the answer on the same line as the question.

show_object

show object(1m) 														   show object(1m)

NAME

       show object - Displays attribute information about the specified object entry

SYNOPSIS

       cdscp show object object-name [attribute-name] [with attribute-name = attribute-value]

ARGUMENTS

       The  full  name of a specific object entry.  The last simple name can contain wildcard characters.  The name of a particular attribute; see
       Description for valid attribute names.  The value of a particular attribute.

DESCRIPTION

       The show object command displays the names and values of the attributes	specified  in  attribute-name.	 You  can  use	a  combination	of
       attributes in a single command. Use a space to separate multiple attributes.  You can use a with attribute-name = attribute-value clause to
       limit output only to object entries whose attributes have values equal to the specified values. If you do not supply  any  attributes,  the
       command	displays  all attributes and their values.  In addition to the following attributes, any application-defined attributes that might
       exist will be included in the output of this command.  The following is a description of object entry attributes: Specifies  the  class	to
       which  an  object  belongs.   Contains  the  version number of the object's class.  This allows applications to build in compatibility with
       entries created by earlier versions.  Specifies the creation timestamp (CTS) of this object entry.  Specifies a unique identifier  for  the
       object being referenced.  Specifies the timestamp of the most recent update to an attribute of the object entry.

   Privilege Required
       You  must  have	read  permission  to  the object entry.  If you specify a wildcard object entry name, you also need read permission to the
       directory that stores the object entry.

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLE

       The following command lists all the attributes  and  their  values  of  the  object  entry  /.:/sales/east/floor1cp.   cdscp>  show  object
       /.:/sales/east/floor1cp

			       SHOW
			     OBJECT   /.../abc.com/sales/floor1cp
				 AT   1991-10-15-15:53:07
			    CDS_CTS = 1991-10-15-19:53:03.00000003/08-00-2b-1c-8f-1f
			    CDS_UTS = 1991-10-15-19:53:03.00000006/08-00-2b-1c-8f-1f
