hi every one , and thank to the forum to help solving my problems with linux
i was commenting in a page that was far from the first purpose so i decided to open this thread to ask some various problems with installing scientific packages . he problem is this : i installed a new package
with all the prerequisites , as written in the manual i tried to run it with the " unix% mpb foo.ctl >& foo.out " after that the comment "(set! num-bands 8)" but the msg was this :
bash: set!: command not found

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

i wonder if the manual is for unix not for linux because i dont knpow whether the key words for unix is different from those for linux???!!!
and also i faced a new problem while running another program : when i try to run it the answer is " the key is off " . is it something related to linux or the msg is just somehting related to the code(the program is a packaged code) i use ?

Hi minaesm, glad to see you finally succeed in the installation. Regarding the command
to me the unix% is the shell prompt so you have just to enter the mpb command. Regarding
in bash the parentheses force the execution of the command in a subshell. But indeed set! has no meaning in bash. To me it looks like a scheme syntax (being scheme another scripting language). Maybe you have to issue this command in an interactive scheme session (you should see a different prompt at some point).

hi every one and tnx for your really useful helps
i have a problem with a scientific package , it plots some structures that it read from a "(file).dat" file ,and it has some examples in itself to become familier with it. when i want to change the parameters i just got the message : " key is off " and i got axactly the same plot that is in it and nothing changes , i think that it should be some thing very simple but i do not know how to solve it to get diffreent plots , i appreciate any kind of help from the side of you .
