Reference Format
Individual source program lines must follow a reference format that the compiler
accepts. There are two choices of reference format: Tandem and ANSI. Tandem
format, an HP extension to COBOL, is less restrictive than ANSI. The principal
differences between the Tandem and ANSI formats are in:
•
Margin locations
•
Permitted line lengths
•
Absence of sequence number and identification field in Tandem format
•
Continuation lines
You can write a COBOL source program entirely in either format or in a mixture of
both. The default is Tandem format. Unless you direct the compiler to accept ANSI
format, the compiler assumes the entire program is in Tandem format.
