COBOL-Importance of 7th Column

SAP HANA + JOBS+Career+Apply NowIn COBOL program coding starts at position 8 and up to 72nd position.

  • There are two areas in COBOL need to focus one is Margin A and the other one is Margin B.

Margin A

It starts from position 8. Usually entries of DIVISION and Para name starts from column 8.

Margin B

We code all procedure division statements, and all other sentences at position 12.

Importance of 7th Column

  • ‘*’ this will be used to give comments. Compiler ignores this line.
  • ‘/’ this is the instruction to compiler. When you want to print the program, the code will move to next page. In real-time projects many people are giving at the end of the para-just for coding clarity.
  • ‘-‘ Hyphen is used for continuation lines
  • Sequence numbers 1-6: It is optional. In some projects giving sequence number in their COBOL code. But in some projects it is not mandatory.
  • ‘D’  we code it at 7th position for debugging purpose. But,this will anyway be ignored by compiler. The usage you can see when you use debugging tools.
