 Subj: BUGS IN 6811ASM               Status: PUBLIC MESSAGE

 I'm still finding bugs in the assembler.

 The  ELSE,    of   IF, .... ELSE,  ....  THEN,,

 was not compiling the correct branch offset for the branch compiled
 by IF,    It was low by a count of 2.

 The definition of ELSE,  must be changed to:

 : ELSE, ( back-adr - here )
         HERE OVER 1- - SWAP C!   ( You cannot use THEN,  )
         ALWAYS, C, HERE 0 C, ;   ( as offset generated is low by 2 )


 I think there was another bug too.... but I forget where.

 It's 1:00 now and I'm going to bed.
