MatchLocalNames
MatchLocalNames is an option for Trace and related functions which specifies whether symbols such as x should match symbols with local names of the form x
$
nnn.
The default setting is MatchLocalNames
->
True.
With the default setting, Trace[
expr
,
x
=
rhs
] will show assignments to local variables whose names are of the form x
$
nnn.
Trace[
expr
,
x
=
rhs
,
MatchLocalNames->False] shows assignments only for the global symbol x.
See the Mathematica book: Section 2.5.10.
Further Examples
This traces assignments to all variables with names of the form x$
nnn.
In[1]:= 
Out[1]= 
This traces assignments only to the specific global variable x.
In[2]:= 
Out[2]=
