Which program did you install? Not all programs will add something to the Applications menu, especially programs designed to be run from a command line.

To see if the program is installed, open a terminal (Applications > Accessories > Terminal) and type the name of the program you are trying to run. For example, you may be trying to run f2c (one of the Fortran77 to C++ tools), so type

f2c

into the terminal and press enter.

Does anything appear? Have you tried looking at the documents for the program in question (try f2c --help in a terminal perhaps or man f2c in a terminal or see if there is any documentation in /usr/share/doc or somewhere else)

I guesss I don't know how to navigate how do I get to usr/share/doc?
When I issue the command in the terminal window I get

usr/share/doc
Error on line 3: illegal continuation card (starts "usr/sh")
usr/sh
Error on line 4: illegal continuation card (starts "usr/sh")

When I type f2c I get
f2c
Error on line 5: nondigit in statement label field "f2c "

Trying f2c -help yields
f2c -help
Error on line 6: labeled continuation line (starts "f2c -h")
man f2c yields
man f2c
Error on line 7: labeled continuation line (starts "man f2")

also how do I display my directories and/or create them - I apologize - I am really rusty

No problem. Unfortunately, I am not familiar with the software you are trying to use, so I can't help on that specifically.

If you have the GUI, if you navigate to /usr/share/doc you can look at the various folders there and hopefully there will be one for f2c which should contain some documentation.
If no GUI, then

cd /usr/share/doc

(cd changes directory to another folder)

then see what is there. .

ls | less

(The | less (pipe symbol followed by less) allows you to scroll through the list which you asked for with the ls command). If you already know the folder is likely to be called f2c, then you could go directly there with

cd /usr/share/doc/f2c

and then use the ls command to list the contents of the folder.

ls -a

It appears there is no man page for the program - which is why you ended up just getting the command back. The help command is prefixed with 2 hyphens (it doesn't show easily in here I know!).

You may like to have a look at the tutorials for the command line stuff - it may help freshen up the commands for you.
There is a good FAQ which has a few links, ranging from the fairly basic to some pretty complex stuff over at -

I suspect that you are probably already an experienced coder, so a quick brush up should be all you need!
