### Description

Each time an error occur, the Scilab error handler records it in internal tables (only the last one is retained). The `lasterror` function allows to get the message, the error number, the current function (if any) and the current line of the current function out of these tables.

This function is useful while using `errcatch` or `execstr`.

The recorded error message may be retained for a further call to `lasterror` using `lasterror(%f)`.

    ierr=execstr('a=zzzzzzz','errcatch')
    if ierr>0 then disp(lasterror()),end
