Modifying a variable name

Specify a variable name for msiGetStatSample to modify.

Similar to msiTocEntry, msiGetStatSample returns "0" or "1". Unlike msiTocEntry, {}

For example:

Input: msiGetStatSample conn_0 var
Output: 1

Input: msiTocEntry some_thread_name var
Output: 0 cannot be
            used.
