Output formatting of dumps on 3800 printing subsystem

You can request a high-density dump on the 3800 through two parameters on the DD statement for the dump data set or on an OUTPUT JCL statement referenced by the dump DD statement:

You can code one or both of these parameters. You can place both on the same statement or one on each statement.

Examples
  
//SYSABEND DD SYSOUT=J,FCB=STD3,CHARS=DUMP  
  
//DUMPOT OUTPUT FCB=STD3,CHARS=DUMP  
//SYSABEND DD  SYSOUT=J,OUTPUT=*.DUMPOT
