How to suppress printing variable name while printing its value in sqlplus?

Question

I am trying to achieve this.

This is my code

var cvar varchar2(20) 
exec :cvar := 'variable value'
print cvar 

This is the current output

PL/SQL procedure successfully completed.


CVAR
--------------------------------------------------------------------------------
variable value

I want to output only the variable value. Not its name or any other output

variable value

I tried all these settings. no luck

SET DEFINE on
SET HEADING OFF
SET VERIFY OFF
SET FEEDBACK ON
SET ECHO OFF
SET PAGESIZE 0
SET TRIMS ON
SET PAGES       1000
SET APPINFO     OFF
SET TIME        OFF
SET TIMING      OFF
SET TERMOUT     ON
SET TRIMS       ON

Answer 1

It is set heading off:

SQL> var cvar varchar2(20)
SQL> exec :cvar := 'variable value'

PL/SQL procedure successfully completed.

SQL> print cvar

CVAR
--------------------------------
variable value

SQL> set heading off
SQL> print cvar
                                   --> see? No heading here
variable value
