$pendingtraps 0 Uses no pending traps. If nonzero, allows

traps that cannot be satisﬁed immediately to

pend until they can be satisﬁed. This is useful

for debugging programs that use dlopen() to

load symbols as it allows setting breakpoints

before the dlopen() call. Similar to $debugrld,

but $pendingtraps does not allow setting

breakpoints in rld. When set to nonzero,

mistyped procedure names cause a pending

trap to be set.

$piaddtohist 1 If 1, adds commands read from ﬁles using the

playback input command to the command

history. If 0, does not add the commands to the

history.

$pid The current process for kernel debugging (-

k).

$pid0 Set by dbx to the process ID of the running

process (also called the object ﬁle).

$pimode 0 If 1, dbx prints the commands read from ﬁles

using the playback input command. If 0, dbx

does not print the commands. In either case,

dbx prints the output resulting from such

commands.

$printdata 0 Used when disassembling. If 1, prints register

contents alongside disassembled instructions.

If 0, just prints disassembled instructions.

$printwhilestep 0 If 0, prints only the next line to be executed. If

nonzero, prints each line that is executed

while it single steps.

$printwide 0 If 0, prints arrays one element per line. If

nonzero, prints arrays compactly (wide).
