i'm writing a program that'll let you do interesting (well, not THAT
interesting) things with the vat.  one of them is rename things.  right
now i create a new variable (0-byte string) with the new name and swap
the location and type.  the only problem is that i can't delete or even
use the old one!  erg, i'm never good at explaining things:

help!

        ld hl,0 ;1 byte didn't work either.
        call _CREATESTRNG

        ;bde=abs addr
        ;swap addresses and type
        ld ix,(current) ;fix new ptr
        ld a,(ix+$02)
        ld (hl),a
        dec hl
        ld a,(ix+$0f)
        ld (hl),a
        dec hl
        ld a,(ix+$0e)
        ld (hl),a
        dec hl
        ld a,(ix+$0d)
        ld (hl),a

        ld l,(ix+$00)   ;fix old ptr
        ld h,(ix+$01)
        ld a,$0c
        ld (hl),a
        dec hl
        ld (hl),d
        dec hl
        ld (hl),e
        dec hl
        ld (hl),b

        ;delete old one
;        ld hl,(current)
;        inc hl
;        inc hl
;        rst 20h ;mov10toop1
;        rst 10h ;findsym
;        call _delvar

running delvar would cause it to copy everything down 2 bytes! (wierd)

oh, (ix) =
;$00-$01 ptr to vat entry
;$02     type
;$03     length of name
;$04-$0C name
;$0D-$0F absolute address
