MACRO & System Variables mapping of original controllers.

I have a 98Vf/4 - OS upgraded to 9.64N about 1 yr back We are/were running some custom software that was originally setup for Fanuc.... but we had running on the old OS.

Admit to being new on haas macro/CNC programming, but I know my way around VB, PERL, JAVA JS, etc... so I'm ok w/ the challenge here.
Where I'm confused:

• 
  What variable ranges are allowed for what OS version?
• My original OS 9.46(? guess) had all these macro ranges when I'd page down, went on and on.
• New CPU and OS 9.64N 1yr later- Matches exactly to the list in the image. Lost 1/3 of so of what would list on the old OS. Which also seems to have caused issues w/ some of those programs I was able to run.

In consulting w/ the author, I began converting all lines where #100-#119 were used. Mapped them to #120-#139 and many more into #520++ Due to limited space and all these things needed I did float up into 540++ (for probe) which one of the program is actually. NON-HAAS!
var conversion is all done.. uploads fine and ready to start some test runs BUT...

OK.. My newb story now laid out, now getting to my question - (Again I'm new) The Author checked my stuff and noted he'd rather I move anything #540++ up into the #600 range. I do not have that any more when I look at the listings on my screen? #599 is the end. Yet many more showed up on the old OS... And that's my million $$ question- Do I have #600-699 or not? My systems stops at 599 and I cannot page down any farther like I used too... (ref: System Variables | Customer Resource Center )

* THIS Image from a renishaw manual exactly matches my system and is the right age to my VF/4 OS

Go the current commands page, then macros page, then hit end. ours stops at 999

Yup... Stops at 599 nada more. I exported the vars file and imported below. 599 is all I get. I wonder if there is a setting or something to turn 'on' something more possibly? This is not making sense.

I cant quite remember but I believe in software version 11 and up they added more macros. There is the 9000 series for M and G programs on the early machines as well.

Thanks Hoss. I am pretty sure that I'm not going to get anything more out of her beyond #599.. I pulled a floppy from this thing in the back slot. found a PC w/ a floppy drive in the basement. (OMG it still booted!) and the Mills BU files (OEM stock as new from the unit) also stopped at 599. sooouuuuu unless there is something I'm missing.. and I guess I was mistaken on the original CPU having more...
BTW- What is the 9000 series for M and G programs mean?

The 9000 M and G are amazing!! Let's say you have a sub plate on your table. And let's say you have a threaded tap holes every square inch. You write a program such as 9001 to use a drill to clean out the holes and assign it M21. So any time you go to mdi and put it m21 , it will call up that program, tool , and offsets and do a drill program to clean out every hole. You can use it for almost any type of program, or subroutines. It's up to your imagination!! It can be used in main programs as well.
