DISPLAY Pic-X-64-field (1 : X-64-Actual-data-length).
<SNIP>
You might try something similar to the following:
05 PIC-VAR-MOVE REDEFINES PIC-X-64-FIELD.
07 FILLER PIC X OCCURS DEPENDING ON
LENGTH-FIELD-S9.
Change the group level (05) to match the same level as the
PIC-X-64-FIELD. Then the LENGTH-FIELD-S9 becomes the name of the field
having the length in it.
Now this NEW group level, PIC-VAR-MOVE dynamically changes in size to
match the size of the table you have defined. So a MOVE using this as
the source will only move the number of bytes given by the length field.
You might also want to modify this to say "OCCURS 1 TO XX TIMES
DEPENDING ON..." to avoid an overflow condition.
Later,
