variables: ″Set″ Variables
Usage Note
The following ″set″ variables have special meanings:
$asciichars, $asciistrings
When set any dbx operation that displays the value of a character or string
will interpret the binary representation of the character or string as ASCII.
$c, $m, $t, $l
Condition, mutex, thread and readwrite lock type variables.
$catchbp
When set, allows for the catching of breakpoints during a next command.
$charset=″destCodePage,srcCodePage″
When set, convert character strings prior to displaying them. Strings will be
converted from the codepage srcCodePage to destCodePage. Note that
destCodePage must be IBM-1047. The default setting is not to convert
character strings.
$current
Defined as a constant with the value of the current thread.
$cv_events, $mv_events, $tv_events, $lv_events
When set, will notify the user when a condition variable object, mutex
object, thread object or readwrite lock type event is processed.
$dll_loads
Causes dbx to recognize that a DLL has been loaded and read the
symbolics for the DLL.
$dll_loadstop
Causes dbx stop in the function that caused the DLL to be loaded, or in the
case of a DLL variable reference, the next source line in the current
function.
$expandunions
Causes dbx to display values of each part of variant records or unions.
$fl_precison
Sets the amount of precision, in bytes, to use when displaying a floating
point value. Possible values are 4, 8, and 16.
