<DD>One of the goals of the <B>ftnchek </B> program is to help users
to write portable Fortran programs. One potential source of nonportability
is the use of variable names that are longer than six characters. Some
compilers just ignore the extra characters. This behavior could potentially
lead to two different variables being considered as the same. For instance,
variables named AVERAGECOST and AVERAGEPRICE are the same in the first
six characters. If you wish to catch such possible conflicts, use this
flag. Default = no. <blockquote></DD>

<P>
Use the <B><A HREF="f77.html">-f77</A>=long-names </B> if you want to list <I>all </I> variables
longer than six characters, not just those pairs that are the same in
the first six. <P>
