What exactly are the errors you mention you're getting?

Also, what do you get when you type this?

filename=command_line_args(count=count)
help, filename
print, transpose(filename)
print, 'Count:', Count

What are you using the following line for?

file='filename'

If you want to extract the first string from the string array returned
by the command_line_args() function, I would use
file = filename[0]
instead.

Apart from that - as it stands, I would say that yes, these lines are
probably right in that I can't find an obvious coding error there, but
it depends on what you're trying to do!

Tell us more :-)
