6.3.2 Directive Syntax

Place each directive on a line by itself, immediately before the COBOL line to which it pertains.

Introduce each directive with a "$" in the Indicator Area (column 7 in standard ANSI source format), followed immediately by the letters "XFD", and then the directive itself. There must be no space between the $ and the XFD. Spaces are permitted elsewhere on the line as separators. For example, the NAME directive looks like this:

    $XFD  NAME = COLOR   

An alternate ANSI-compliant way to introduce a directive is with an asterisk (*) in the Indicator Area. In this case, you begin the directive with the letters "XFD" and enclose the entire directive in double parentheses. For example:

    *(( XFD  NAME = COLOR ))   

There must be no space between the asterisk and the double left parentheses. Spaces are permitted elsewhere on the line as separators.

You may use either form of the directive syntax (or both) in your applications.

Two or more directives that pertain to the same line of COBOL code may be combined on one comment line. The directives should be separated by a space or a comma. For example, to specify both USE GROUP and NUMERIC at the same time, you would add this line:

    $XFD USE GROUP, NUMERIC   

or

    *(( XFD USE GROUP, NUMERIC ))
