Continuation of a format

General Rules:

  1. Application generation treats most format specifications beginning with COBOL edit mask characters as a valid COBOL formats, and passes them directly to the generated program. However, AMB translates an A, followed by a numeral, as follows.
    A8  generates  PIC A(8).
    
  2. Enter only the level 66, 77, or 88 numbers; do not enter other level numbers, such as 01, 05.
  3. Enter one data element name per line only. A data element name can be a valid COBOL name of 1 - 30 characters, or expression introduced by one of the Customizer default symbols.
  4. You do not need to code the word PICTURE in a picture clause. A PICTURE clause format can be a valid COBOL format or a AMB Data Structure Editor shorthand picture format.
  5. If you do code the PICTURE or PIC, use only valid COBOL syntax within the PIC clause - do not use the AMB shorthand picture format.
  6. You can continue the data structure on multiple lines wherever a space occurs, for example:
    WORK1-FIELD1      X(13)
    ... V'13 CHARS LONG'
    WORK1-FIELD2      X(120)
    ... VALUE 'A LONG LITERAL MAY
    ...  BE CONTINUED ON ONE OR
    ...  MORE LINES'
    
  7. AMB treats the Data Structure Editor formats 99, A9,N9,S9, and V9 as valid COBOL formats and passes them directly to the generated program (as PIC 99, PIC A9, and so on). If, however, you want the generated COBOL to be PIC 9(9), PIC V(9), and PIC A(9), use the Data Structure Editor formats 9(9), V(9), and A(9).
  8. If a format includes an Customizer variable followed by additional format syntax, use a plus sign (+) to separate the Customizer variable from the additional syntax. During processing, AMB eliminates the plus sign and concatenates the suffix onto the syntax. For example:
    9&variable+V5 generates PIC 9(&variable)V9(5).
    
  9. Distinguish Vvalueclause from V as an implied decimal point.
    • For Vvalueclause, precede the V with a space and immediately follow it with the valueclause.
    • For V as an implied decimal point, use no space before or after the V. For example:
      N8V4 generates PIC 9(8) V9(4). 
      N8 V4 generates PIC 9(8) VALUE 4.
      
  10. Never code comments within Data Structure Editor constructs.

Example:

The following illustrates using indentation to create level numbers:
