Specifying a condition for a field or for more than one keyword
Specifying a condition for a field or for more than one keyword
If you specify a condition for a field, the field name (or the constant) and the last (or the only) indicator must be on the same line.
If you do not select the field for an output operation, no keywords specified for that field are in effect, regardless of how the condition for the keywords is specified. For example, in the following figure, FLDA is selected if either indicator 01 is off or indicator 02 is on. If FLDA is not selected, any keyword associated with that field, such as DSPATR(HI), is ignored.

If the condition applies to keywords on more than one line, you must use keyword continuation for the indicators to apply to all keywords. You can use a plus (+) or a minus (–) sign as a continuation character. For more information about keyword continuation, see Rules for DDS keywords and parameter values.
