That's the problem with these newbie z/VM sysprogs -- they don't want to 
look at the CP source code!    ;-)

Richard,

Every reference I've ever seen to SECLABEL is for printed output.  On 
systems set for B1 security levels, one can set a "security label" to 
print at the bottom (or top -- don't remember) of every hardcopy page, 
such as "TOP SECRET" or "Internal Use Only" (establishing a different 
meaning to "increasing your fiber consumption").

Since it's security related, it makes sense that an ESM may have 
interfaces.  Check for spooling related settings.

I've modified the 8-byte "SECLABEL" field here to contain the current 
accounting code when output is spooled.  That SECLABEL field is then 
passed via NJE to the z/OS systems that print the output - permitting 
accurate billing. for things actually printed.
