If the value of  INDEX-TBL03 is something greater than 400, then it will cause 
index03 to point to memory past TBL03 which would be TBL04.  Check for that and 
see what's in  INDEX-TBL03.

ok,  now I'm really confused.

I put a watch on the variable to see when it gets changed (sign in the
middle of a packed field)

this is what I found:

Given the following working storage definitions:

      01  TBL03.
          02  TBL03A OCCURS 400 TIMES INDEXED BY INDEX03.
            03  TBL03-LLL   PIC 9(04) COMP.
            03  TBL03-ADDR  PIC X(25).
          02  INDEX-TBL03  PIC 9(04) COMP.

      01  TBL04.
          02  TBL04A  OCCURS 200 INDEXED BY INDEX04.
            03  TBL04-INGREDIENT  PIC 9(06) COMP.
            03  TBL04-PRICE       PIC 9(02)V9(04) COMP.
            03  TBL04-MEASURE     PIC X(10).
            03  TBL04-DESCRIPTION PIC X(30).
          02  INDEX-TBL04        PIC 9(03) COMP.
          02  INDEX-TBL04-LO     PIC 9(03) COMP VALUE 001.

my watch told me that TBL04-INGREDIENT(3) changed after executing this
line:

        SET INDEX03 TO INDEX-TBL03
-->        MOVE M2REST OF MENUS-REC TO TBL03-LLL(INDEX03)
        SET INDEX03 TO 1

how the heck does that happen?  The tables are in 2 separate spots, but
changing one overlays the other?

sounds like a bug to me....
