user of filer?  or Uses of filler?
Did you face any interview question like that?
FILLER can be used to align numeric variables to word boundaries for performance improvement.
When you intialize a group variable, filler fields are unaffected. This can be used to our advantage. for example in date fields-
| Code: |
01 date-fl.
05 mm pic xx.
05 filler pic x value '/'.
05 dd pic xx.
05 filler pic x value '/'.
05 yy pic xx. |
By declaring this variable we need not move '/' as a separator even if we use and initialize date-fl in program many times. |

Hi
Filler is the purpose of declaring the variable with out specify any name.
Ex:
01 Todays-Date
02 Todays-CCYY Pic X(4)
02 Filler Pic X(1) Value '/'
02 Todays-MM Pic x(2)
02 Filler Pic X(1) Value '/'
02 Todays-DD Pic x(2)
move '2007' to Todays-CCYY
move '09' to Todays-MM
move '14' to Todays-DD
Display Todays-Date
It display's '2007/09/14'. It occupies the size of 10 bytes.
In Your Example:
WS-ORD-DATE is the Numeric Variable and size is 8 bytes.
FILLER REDEFINES WS-ORD-DATE means :
The Programmer using the same memory of WS-ORD-DATE and the expanded dataitems for filler will use to change the values.
10 WS-ORD-DATE-CC PIC 9(02).
10 WS-ORD-DATE-FMT PIC 9(06).
10 FILLER REDEFINES WS-ORD-DATE-FMT.
15 WS-ORD-DATE-YY PIC 9(02).
Ex: If the value of WS-ORD-DATE is '20070914'
Then If you want to display the Century
Display WS-ORD-DATE-CC. It display's 20
Display WS-ORD-DATE-YY . It display's 07
Like that it will be useful
Regards,
Chiranjeevi. |

Bad example. Filler is never used at 01 or 77 levels. |

| 77 levels might be hard to justify as FILLER, but 01 are quite often FILLER (usually without the VALUE).... |

FYI, you don't need to code filler with the latest cobol compiler in some situations
01 Pic X will work. |

Hello,

This is quite common with the FILLER redefines another 01 but doesn't need a name. . . |

You've done it. You made me curious. Can you give some sample code how to use a "01 filler" definition? |
