On this case let the column1 for abv. and two for name..

On interactivechange/keypress method try +or- something as:

procedure interactivechange
if  len(allt(this.value))<3
    return
endif
if  type("this.cmychoice")="U"
    this.addproperty("cmychoice", "")
endif
nwlen = len(allt(this.displayvalue))
for i = 1 to this.listcount
    if  substr(this.displayvalue,1,nwlen)=substr(this.listitem(i,2),1,nwlen)
        cnewvalue                         = this.listitem(i,2)
        this.cmychoice                    = cnewvalue
        this.displayvalue                 = cnewvalue
        This.selstart                     = nwlen
        This.sellength                    = len(allt(this.displayvalue))-nwlen
    endif
endfor

procedure keypress
LPARAMETERS nKeyCode, nShiftAltCtrl
if  nKeycode=13
    if  type("this.cmychoice")="U"
        return
    endif
    for i = 1 to this.listcount
        if  this.cmychoice=this.listitem(i,2)
            this.value        = this.listitem(i,1)
            this.displayvalue = this.listitem(i,1)
        endif
    endfor
ENDIF
