SCREEN COBOL Source Program
Compaq NonStop™ Pathway/iTS SCREEN COBOL Reference Manual—426750-001

Comment Lines
The positions following Margin R (73 through 80) represent the identification field.
Their contents, which can include any ASCII character, are treated as a comment, and
have no effect on the meaning of the program.
Figure 2-2
shows the ANSI standard reference format.
•
Division, section, and paragraph headers must begin in Area A. The first sentence
of a paragraph can begin on the same line as the paragraph header, provided at least
one space follows the period terminator of the paragraph name.
•
In general, SCREEN COBOL ignores the distinction between Area A and Area B.
The lexical elements of a source program can occur anywhere between Margin A
and Margin B.
•
Level numbers 01 and 77 must begin in Area A.
•
Level numbers 02-49, 66, and 88 can begin in either Area A or Area B.
•
An * or / in the indicator field indicates a comment; a - indicates continuation;
a ? indicates a compiler command line. If any other character appears in the
indicator field, the last character in the preceding line is assumed to be followed by a
space.
Comment Lines
Comment lines can appear anywhere in a SCREEN COBOL program. Comment lines
are indicated by an asterisk (*) or forward slash (/) character in the indicator field, which
is column 1 in the Tandem standard reference format and column 7 in the ANSI
standard reference format. These special characters indicate that the entire line is a
comment.
When a listing of the program is printed, with comment lines indicated by a forward
slash (/), a page eject is performed before printing the comment line.
