That is not a true statement. Here is an example:-
Code:
$ cat script.ksh 
#!/bin/ksh

conn_str="user@passwd@dbinstance"

sqlid=$(
        sqlplus -s $conn_str << EOF
        set echo off head off feed off pagesize 0 trimspool on linesize 1000 num 20
        @sqlid.sql
EOF
)

print $sqlid

Code:
$ cat sqlid.sql
select sql_id from v$session where sql_id is not null and rownum < 2;

Here is the output I got:-
Code:
$ ./script.ksh

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. ATTRIBUTES
