Just type 'new' on the command-line before pressing PF2, or change PF2 to "split new" and you can have up to (site_dependent!) 32 screens. Default is 8 I think.
Likewise, you can use PF9 to swap between more than two screens via:
LIST PF9 (SWAP LIST) - shows all screens in a pop-up
PREV PF9 (SWAP PREV) - previous screen
NEXT PF9 (SWAP NEXT) - next screen
Alternatively, you can give screens a name via the SCRNAME command and use SWAP name
