I just started in a company that uses mainframes.
I got access last week. A lot of things are not very well documented, and I don't know much about mainframes in general.

I may be explaining this wrong but it seems like there are several environments and then each environment has several apps that are launched by using the clist app name command.

So I launch rumba and it gives me a logo screen.
From there I can either type in an environment. cv02vtm
this will bring me to a log in prompt.
after I log in I type in the clist appname and I get in.

I found that going a different path.
logo screen
hit enter
select clss1 (cid users)
log in
then I get a command prompt I can type in list
This gives me a list of what I think are environments.
cv01, cv02 etc..

My question is, how do I get a list of apps/ clists that I can run in each one?
It seems to be a basic question but I cannot find an answer to it.
In other words, I know because someone told me cv02 has app1 and app2 in it. So if I type in clist app1 I get that to work.
but how do I see if there are other choices in cv02 other than the 2 people "know" about?

I tried to straight telnet into the box, but it asks for application before I can continue and I don't know what to give it as a response.

What you are calling an environment is either an LPAR on a machine, or a totally separate machine. And nobody on this forum works for your company (that we know of), and hence nobody on this forum can help you with what you are asking. Only someone working AT YOUR SITE could possibly help you. Different sites are set up in different ways, and what works for one will not work at another. Many mainframes have security set to prevent application programmers from exploring the system too much, so asking your site support group is the best way to find out what you want to know.

This, again, depends upon your site and hence we have no idea what would be valid for your site.

I was hoping there was a canned thing like list that would work for finding all the clists on a lpar/machine.

based on your post, I take it might be intentional there is no way to pull a list.

I gathered it was a file in a library that was invoked, but could not find a way to browse a library or direct the list command to a specific lpar.

I am working my way to finding a dev person, but haven't gotten any names yet.

IF they didn't lock it down, is there some built in that might work to list these items?

Most sites have a set of fairly standard libraries where things will be placed (such as SYS1.PROCLIB, SYS1.PARMLIB, SYS1.SYSPROCS) but a common site customixation is to place an identifier into the name so SYS1.PROCLIB might be SYS1.<lparname>.PROCLIB. Furthermore, many (but by no means all) sites use session managers such as SUPERSESSION or CA-TPX to control access to various applications / LPARs. You could use TSO/ISPF to look at the libraries for each LPAR at your site, but since each LPAR runs independently of the other LPARs, there's not really any easy way to find out what is available on each LPAR -- other than talking to your site support group and asking.

You don't want a dev person, anyway. You want a site support person -- development on mainframes is usually handled by a completely separate group and development people usually have very restricted access to the system.

Thanks.
I am working on getting access to ispf so that helps once I can see in vs the app interface.

Thanks for the other tip. I will start asking who the site support person is instead of dev.
