You can't do what you want with the host debugger. The host debugger syntax 
is quite limited. No amount of messing with compound statements, 
parentheses, etc. allowed me to make this work. It doesn't complain about 
the AND because it has been built to allow expansion but currently does not 
support complex expressions. You are restricted to the same sort of 
expressions that can be specified on the EVAL statement. You would not 
expect:
        EVAL  space and library  
to work, would you? Although  there is a valid case for:
        EVAL space = 'ABC' and library = 'XYZ'
but that's not supported either.

Note that you can use built-in functions (the DEBUG ones, not the RPG ones) 
in a BREAK statement. For example:
           BREAK 396 WHEN %SUBSTR(P_JOBNUM 1 3) = '2AC'

Given Rochester's penchant for GUI this and GUI that I would not expect any 
improvements in the host debugger. If you want a modern debugger then look 
at CODE/400 or Eclipse or the IBM Distributed Debugger.

Simon Coulter.
