hi, developers, i've written a small program to list all tags in a swf file, then remove some unknown tags by some encryption software. But i have some problems here. RECORDHEADER definition have two types, short one for tags with 62 bytes or less and long one for tags with more bytes. But it seems there are some undocumented rules, e.g. FLASM said,
   if (length >= 63 
      || type == TAG_SOUNDSTREAMBLOCK) { 
         long length, and also workaround for a really strange bug in flash player: 
         the above tags must always have long length to work 
      flputShort((type << 6) + 63); 
   else { 
      /* short length */ 
      flputShort((type << 6) + length); 
Is it true, or even some more rules here? Thanks very much for kindly helps.
