A few things I noticed:

:.Get Next Entry
:.Returns 1 if End of Vat or 0 otherwise

:Lbl VX
:P-{P-6}-6->P>={E982E}r
:Return

Should this be <=? (I actually think a simple = might suffice though)

Quote
:.Get Pointer to current entry data
:Lbl VD
:{P-4}r
:Return

I think this should be {P-4}rr, since it is stored backwards.

Quote
:.Get Pointer to current name length
:Lbl VNL
:{P-6}
:Return

This actually returns the length itself, not the pointer.

An example would be good. This could definitively become useful :)

Awesome thanks Quigibo! This works perfectly. I just tested it and had no errors :)
 EDIT: This is what i did:

Code: [Select]
:sub(VI)
:
:Lbl L
:If sub(VT)=5
:  For(A,1,sub(VNL))
:    Disp {sub(VN)-A+1}>Char
:  End
:  Disp i
:End
:If sub(VNX)
:  Goto L
:End
:Return
:
:Lbl VI
:{E9830}r->P
:Return
:
:Lbl VNX
:P-{P-6}-7->P>={E982E}r
:Return
:
:Lbl VT
:{P}
:Return
:
:Lbl VD
:{P-4}rr
:Return
:
:Lbl VA
:{P-5}
:Return
:
:Lbl VNL
:{P-6}
:Return
:
:Lbl VN
:P-7
:Return

And it worked perfectly.

Also, since when is the 2nd+8 key "appv?" Has it always been the appvar key?
I just noticed this lol

EDIT2: Ok thats cool. It only does "appv" if you have an Axe header :D

Yeah that "v" token was changed to "appv" because there is already another lowercase "v" token available when lowercases are enabled. I wonder why TI used two different tokens for the exact same symbol x.x.

The new token names were implemented in version 0.3.0 I think. I was not a big fan of them at first because I thought QUigibo would just plain rename every existing commands, confusing those who have been used to the old syntax for a while, but finally only 3 or 4 old commands were renamed and all new tokens names added later were used only for new Axe commands/symbols/modifiers, so for now, the only issue I had was finding some in the CATALOG menu because they no longer show in alphabetical order.

Yeah i also noticed that with an Axe header, the lowercase "u" token is "var" and the lowercase "w" token is "grp"

Ossim!

Yeah those were changed a bit later. It is mostly for readability, as using w for group prefixes for example would confuse people and make it hard to remember the syntax. In fact, weird syntax and cryptic names are something that turns me off from z80 assembly source x.x

Yeah. At first I did not realize this could be possible, but then I remembered the Français APP that translated all calc menus in French. For brand new commands, since whenever there's an Axe header at the top of the program the new tokens are enabled, it makes code much easier to read. RectI() looks MUCH more like a rectangle drawing command than rref(), for example.

i have a question with quigibo's routine. how do you retrieve the length of the data of a vat entry? subtracting two pointers to the vat entries themselves doesn't work, and neither does subtracting the pointers to their data. suggestions?

The "pointer to the data" in the VAT entry actually points to the two bytes containing the size of the data. Just store that as a two-byte number.

another question: is there any way to allocate more room for a variable you have accessed? so if i wanted to add a line onto a program, could i do it in axe by simply changing the size bytes of the variable in the VAT?
