[OS X TeX] Numerical commands

[Alain Schremmer]

This is half off-topic:

With arrayjobx, I am defining commands such as, for instance, in 4.sty:

\newarray\IV            %4
\readarray{IV}          %Chapter 4. From Local Graphs to Global Graphs
	{% begin array
		%4-1
			CheckableItem1
		&4-2
			CheckableItem2
	[...]
		&%4-50
			CheckableItem50
	}%end array

I am using these commands as below and things work well but I was  
wondering if there might be a way to generate automatically the  
command names from the file names, for instance the command
	\IV
from the file name
	4

But the only thing I could think of, namely using
	\Roman{\jobname}
naturally does not work.

Hopeful regards

I use these commands in files such as

%!TEX root = ../CheckableItems-controls/\jobname.tex
%================================================
	%Row			Chapter IV
			\textbf{\finkbase}
		&	
		&	\textbf{From Loc Graphs to Global Graph}
		&	
		&	
		&	
		&	
		&	
		\\
\hhline{--------}%====================================
	%Row			Chapter IV
			\finkbase
		&	1
		&	\IV(1)
		&	
		&	\checkmark
		&	
		&	
		&	
		\\
	%Row			Chapter IV
[...]
			\finkbase
		&	50
		&	\IV(50)
		&	
		&	
		&	
		&	
		&	
		\\
		\midrule

where %!TEX root calls the file

\documentclass[11pt]{book}
	\usepackage{../StyleSheets/Preamble}
	\usepackage{../StyleSheets/CheckableItemsLists/\jobname}
\begin{document}
	\setlength\LTleft{-20mm}
	\begin{longtable}{|c|c|l|c|c|c|c|c|}
