[CM] format error when reading SPEAR files

[Denis Fitzpatrick]

In using the latest Grace executable (3.5.1) and trying spectral.sal 
from http://camil.music.uiuc.edu/Classes/404A2/, I get format-error when 
executing:
define variable log-frames = import-spear-frames("log-drum.txt")
the file is in the working directory.  I do get the same message when a 
use a file name for a non-existent file, however.
Any ideas?
