Question A problem with setting up Variables (in RDGEN)


I have installed RDGEN which comes with VPFIT package.
When I run the program it says:

"Failed to find help file"

But I ran the program from its main directory where all the
files including help files exist.

I think maybe the problem is because of this that THEY say:

"Some environment variables should be set before starting RDGEN".

But I do not know what does this mean and how to do that.

These are the variables:


Would it be possible for you to tell me what does SETTING VARIABLE
means in this case?

With best regards,

Well, that might indeed be your problem! set the environment variables and see what happens..

environment variables are something like global settings, very much like Windows Registry. e.g. this is where your Linux environment is set up. HOME, DISPLAY, USER .... all these are environment variables used for example, Home directory, display, user name/uid respectively...

Here's how you set an environment variable:

using the bash and Korn shells:
#export var=some_value

using the C shell, as far as i remember:
#setenv var some_value

where var is the name of your environment variable and some_value is the to-be-set value.
