this is the type
----------------

TSpellsTag = class
     mults: array[1..32] of shortstring;
     times, spell, spellbook: array[1..256] of shortstring;
   end;

var aspells: TSpellsTag

(aspells is a global var)

this is the first usage
-----------------------

aspells.spell[order]:= copy( line, 1, idx );

order is 100% = 1, line is a string(nonempty), and idx is a nonzero
number (greater than 0 because this line is called after idx is more than 0)

this is the error
-----------------

Project spellconv.exe raised exception class EAccessViolation with
message 'Access violation at address 0040449E in module 'spellconv.exe'.
Write of address 00012004'. Process stopped. Use Step or Run to continue.

i get the same error even if i try something like aspells.spell[1]:= '***';

i just can't get what's wrong.. please help me.. i use delphi 6 with
winxp sp2..

thanx
