Details:

The current line being executed during debugging is available by calling
dbwhere() and is also printed out at the debug prompt.  The line number is not
accurate if the statement being debugged is an "if" or "switch" statement. 
Instead of advancing to the next branch of an if/elseif tree the pointer
remains stuck at the first line containing the "if" statement.  A similar
thing happens with switch statements where the pointer remains stuck at the
line containing the "switch" statement and each dbnext causes the next "case"
to be evaluated.

Sample code uses the attached dbgtst.m file.

Example:


dbstop dbgtst
dbgtst (1,5,10)
dbnext
<RETURN> as many times as necessary to step through the code
         and monitor the current line being debugged.
