sqlplus returning value - remove carriage return '\r' - Please help
Guys - Simple code, i am trying to get a number back from sqlplus call to a query. After that, i need to use that number in a loop.
---------------------------------
#!/bin/ksh
VALUE=`sqlplus -silent sh/password@sh <<END
set pagesize 0 feedback off verify off heading off echo off
select max(sequence#) from v\\\$log_history;
exit;
END`
$VALUE=$VALUE + 1
---------------------------------
Problem is, as soon as i use the variable returned from the sqlplus call, it gives me the following error:
bash: $'184\r=': command not found
I have gone through any number of code syntax and i still need help getting this \r guy out of the variable into a new one so i can do some operations on it.
Any help is "GREATLY" appreciated
---------- Post updated at 04:51 AM ---------- Previous update was at 04:35 AM ----------
I am guessing this problem will not be resolved if i spool the output to a file and read it back in?
Any help is appreciated.
Thanks,

break(1) User Commands break(1)
NAME
break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until loop
SYNOPSIS
sh
break [n]
continue [n]
csh
break
continue
ksh
*break [n]
*continue [n]
DESCRIPTION
sh
The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.
The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.
csh
The break utility resumes execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current
line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.
The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.
ksh
The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified, then break n levels. If n is
greater than the number of enclosing loops, the outermost enclosing loop shall be exited.
The continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-
th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.
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 that follow 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 also that word splitting and file name genera-
tion are not performed.
