LaTeX datatool problems

Question

I'm using datatool package in a LaTeX document. I use it to write labels. I have addresses in a CSV file.

The problem is that I'm unable to write more than 25 labels. It seem like if datatool can't load more that 25 lines from CSV.

Any idea?

This is the .cvs file:

nome,via,,cap,localita,prov
nome,via,,cap,localita,prov
nome,via,,cap,localita,prov
nome,via,,cap,localita,prov
nome,via,,cap,localita,prov

and this is the code:

\documentclass{letteracdp}

\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{datatool}
\usepackage[usenames]{color}

\begin{document}
\DTLforeach*{indirizzi}{%
\nome=nome,\cognome=cognome,\via=via,\civico=civico,\cap=cap,\localita=localita,\prov=prov,}{
%
\begin{letter}{\emph{\textbf{\nome \space }\\\via\space \\\textbf{\cap},\space \localita\space  \prov}}
%
\end{letter}
}
\end{document}

Answer 1

The CSV file is wrong, as it misses the header; moreover you are declaring more fields than are contained in the records. Adding the line

nome,via,civico,cap,localita,prov

as the first in the CSV file and correcting the command into

\DTLforeach*{indirizzi}{%
\nome=nome,\via=via,\civico=civico,\cap=cap,\localita=localita,\prov=prov}{%
\begin{letter}{\emph{\textbf{\nome \space }}\\
  \via\space\civico \\
  \textbf{\cap},\space \localita\space  \prov}
\opening{Dear \nome}
Some text
\closing{Best regards}
\end{letter}
}

the file can be processed regularly. I tried with 49 lines, surely more can be managed.
