Determining the current settings of environment variables

If you do not know what the current settings of specific environment variables are, you have two methods you can use to check settings. You can also use these methods if you want to verify that changes you have made are in effect. You must start either an ISPF shell session, or an OMVS session before you issue the commands:

To determine the setting of a specific environment variable, use the echo command. For example, to verify the setting of the Infoprint XT PATH environment variable, enter:
```
echo $PATH
```

To verify the settings of all environment variables, use the printenv command:

printenv

The operating system returns information similar to this:
