What function returns some number of characters on the right or left
of a string? i.e. if I have the string 'filename', is there a command
like Left('filename',4) = file? Thanks.

one of the many solutions

% the outset
     s='1234-5678';
     nl=4;
% the engine
if nl <= length(s)
     s=s(1:nl);
% -or- depending upton the size of <s> and <nl>
% s(nl+1:end)='';
end
% the result
     s
