To est?
Ja snachala proboval naprjamuju(Memo1.Text[n]:=Succ(Memo1.Text[n])). Ne proshlo,

Lines.BeginUpdate/EndUpdate

читать про отличие char (Text[n]) от string (var s: string);

в твоем случае юзать либо [2] либо

var i:integer; s:string; begin i:=memo1.selstart; s:=memo1.text; s[1]:="a"; memo1.text:=s; memo1.seltext:=i; s:=""; end;
