Subscripts are used to indicate the type of arguments as follows:
logical$_L$, integer$_i$, real$_r$, double precision$_d$, complex$_z$,
character$_c$, and subroutine or unknown external$_x$.  The text of
arguments indicates how it is used: {\bf defined} (value may also be
referenced), {\em referenced} (no value assigned), possibly defined or
referenced uses the normal font, {\scriptsize not used}, and
\uline{external name}.  Arrays are given in upper case.  The decorations
for the arguments were obtained automatically using the software described
in Chapter~19.7, while the text for the arguments was obtained using a
program that examines the \LaTeX \ files.
