EMC mystery error?

Well, the RTLinux demos work well. The 10/8/99 version of emc is
installed, and the ./sim programs work fine, but I'm now getting the
'nknown option: '-

Usage: csh [ -bcdefilmnqrstvVxX] [arguement....]
error that Tim G. had
when he first tried running the 64step378 stepper test stand file. I
have tried the cut and paste method from the sim program, with no luck.
I tried changing the chmod settings of the file to match those in the
sim program, again with no luck.
Any tips from those who have gone before?
