chgvar as400

 chgvar command in clp
Change Variable (CHGVAR)


       the dec variable not send directly to output in clp. so we can change it into char        
      it converts dec variable to char variable.
              

  
The Change Variable (CHGVAR) command changes the value of a Control
Language (CL) variable or part of a character variable.  The value
can be changed to the value of a constant, to the value of another
variable, or to the value gotten from the evaluation of an        
expression or a built-in function.  Expressions and built-in      
functions are described in "Expressions in CL Commands" in the CL 
concepts and reference topic in the iSeries Information Center at 
http://www.ibm.com/eserver/iseries/infocenter.  Also, implicit    
conversion between decimal and character values is performed by the
rules given in the VALUE parameter description.
