See post #5, line 1.



EDIT: How far would this get you (zeroth approximation):
Code:
while IFS=, read agname tablename
  do    exec  > $BASEDIR/${agname}_retrieval.ksh
        echo "while read IFS=, read docname agname"
        echo "do"
        echo "get -G \${agname} -i \"where doc_name like '\${docname}%'\" -o \${agname}"
        echo "done < $BASEDIR/data/${agname}/${agname}_docnames.del"
        exec 1>&2
   done < $BASEDIR/output/$STEP1_OUTPUT


EDIT: or (first approximation)



Code:
while IFS=, read agname tablename
  do    cat <<-EOTXT  > $BASEDIR/${agname}_retrieval.ksh
        while read IFS=, read docname agname
        do
        get -G \${agname} -i "where doc_name like '\${docname}%'" -o \${agname}
        done < $BASEDIR/data/${agname}/${agname}_docnames.del
        EOTXT
      done < $BASEDIR/output/$STEP1_OUTPUT

shift

shift(1)							   User Commands							  shift(1)

NAME

       shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words

SYNOPSIS

   sh
       shift [n]

   csh
       shift [variable]

   ksh
       * shift [n]

DESCRIPTION

   sh
       The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1.

   csh
       The  components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable
       not to be set or to have a null value.

   ksh
       The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can  be  any  arithmetic  expression  that
       evaluates to a non-negative number less than or equal to $#.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
