SummaryError if \DTLnewdbentry's third argument is an empty macro

Report

Hi,

the bug nr 18 (xkeyval incompatibility) has in fact nothing to do with xkeyval (sorry).

It appears that if \DTLnewdbentry's third argument (value of the identifier key) is an empty macro, the following error occurs:

Runaway argument?
\@nil \ifnum \@dtl@numgrpsepcount >-1\relax \if@dtl@numgrpsep \ifnum \ETC.
! File ended while scanning use of \@dtl@checknumericalstart.

The joind MCE shows the problem:

  \DTLnewdbentry{mydata}{Surname}{\test}%
is OK as long as \test is a non-empty macro.

MWE

\documentclass{article}
\usepackage{datatool}
%
\newcommand{\test}{}
%
\begin{document}
%
\DTLnewdb{mydata}%
%
\renewcommand{\test}{Doe}
\DTLnewrow{mydata}%
\DTLnewdbentry{mydata}{Surname}{\test}%
%
\renewcommand{\test}{}
\DTLnewrow{mydata}%
\DTLnewdbentry{mydata}{Surname}{\test}%
\end{document}

Evaluation:

This is now fixed in version 2.14.
