Clarification wanted on G83 G98/99

[Al_The_Man]

I have had (I think) a bug in the Acroloop software Macro's I am using and before I delve in to correcting the code, I would like to get the recognized function of the G98 & 99 as applies to the G83 peck drill.
I does not seem to work at all.
I believe the G99 returns the drill to the R point and the G98 to the Initial Point.
What I often need to do is Drill a series of holes with G83 and between hole positions, raise the Z over a Jig height, which I am assuming is meant by initial level.?
If this is the correct use, Is the Z positioned prior to the G83 in order to set the Initial Point?
And if so what is the normal retract point between pecks?
Is there a protocol/order in which the commands are given?
My version for some reason, always retracts to Z0 during pecks and move between holes, so there is a big bug in the Macro somewhere.

I only use Haas so I don't know how useful these comments are.

Yes G98 is initial point return, G99 is R plane return.

I set my initial point immediately prior to the G83 and have it large enough to clear fixtures.

Between pecks the return can be to the R plane or a Setting can be changed so the peck return goes above the R plane. This Setting is so you can put the R plane right at the workpiece to avoid drilling air but still have the tool lift high enough to clear chips and let coolant into the hole.

There are other things for; 'I' Size of First Cutting Depth, 'J' Amount to Reduce each Peck, 'K' Minimum Peck, Pause, 'L' Number of Repeats, 'Q' Cut-in Value, 'P' Pause after final peck.

It does not seem to matter which order the values are placed on the G83 command line.

Thanks, I have looked at my G83 macro code and see it is lacking an a few areas, I do not have the I or J or K, I will have to write this in if I want it.
Unfortunatly Acroloop sold the line to Parker when these routines were being developed so I am going to have to complete them myself.
The Initial level is not being recorded, it just returns to Z zero.
I have also attached a file I downloaded some time ago if any one wants it, a macro from Hardinge for inclusion of dwell to replace the G74.
Thanks
