PARAMETERS=USED, the default, specifies that only those PARAMETER constants which are actually used in the program unit are made known to the debugger.
PARAMETERS=ALL specifies that all PARAMETER constants are made known to the debugger. If many PARAMETER constants are defined this can greatly increase the size of the object module and executable image.
Controls whether the debugger receives local symbol definitions
for user-defined variables, arrays, (including dimension
information), structures, PARAMETER constants, and labels of
Unless /DEBUG=PARAMETERS=ALL is in effect, only those PARAMETER constants actually used in the program unit are made known to the debugger.
Controls the production of an address correlation table so that
the debugger and the run-time error traceback mechanism can
translate virtual addresses into source program routine names and
compiler-generated line numbers.
Same interpretation as (PARAMETERS=ALL,SYMBOLS,TRACEBACK).
Same interpretation as (PARAMETERS=USED,NOSYMBOLS,NOTRACEBACK).
