You can define any library required by the environment. To differentiate the libraries specified, a library TYPE column is included on the Application Libraries panel. When defining libraries, you must specify their types. The valid library types are:

• ISPF (for ISPF files)
• CLIST (for CLIST files)
• EXEC (for REXX files)
• INPUT (for any other file with the intended use of input during invocation)
• OUTPUT (for any other file type with the intended use of output during invocation). Only one data set can be specified for the OUTPUT library type.
