I would suggest doing the cleanup others have already pointed out, include more
comments, and use mixed case i.e.
SYS1.PARMLIB(IEAOPTH1) - 01.09 Member IEAOPT

These are for our systems currently on z/OS 1.9
Why be stingy with comments or USE ALL UPPERCASE?
In a future release of z/OS I would like to see IBM raise the default for ERV
significantly perhaps to 50K, change the default for CPENABLE on a new z/OS
release since they don't make BASIC mode processors anymore, change the default
for HiperDispatch since it is recommended to be on.
Different thread but HiperDispatch is actually quite good with large n-way
machines. Two z10's and both are running with HiperDispatch.
Yes
