# where

get current instruction calling tree

## Calling Sequence

    [linenum, callername] = where()

## Arguments

linenum

  a column vector of integers

callername

  a column vector of strings

## Description

`[linenum, callername] = where()` returns `linenum` and `callername` such as current instruction has been called by the `linenum(1)` line of function `callername(1)`, `callername(1)` has been called by the `linenum(2)` line of function `callername(2)` and so on.

`callername(i)` is in general the name of a function but it may also be `"exec"` or `"execstr"` if instruction lies in an exec file or an execstr instruction.

## Examples

    function foo()
             [a,b] = where()
             disp("Line:")
             disp(a);
             disp("Function:")
             disp(b);
    endfunction

    function bar()
             function beer()
                      foo()
             endfunction
