[SAC-HELP] Cannot Exit Plot

[rc202388 at ucla.edu]

Hello,

I am working with SAC currently and when I have a
plot open, I cannot close it no matter what.
I tried the 'quitsub' command but it is giving
me a "sh:quitsub not found" error which is strange
because I tried 'fft' and that worked. I am trying to
quit the plot because I want to change directory but
as long as a plot is open I don't think it will let me.
What can I do?

Thank you for your help.
