Usage notes for FD

Some of the FD keywords do not apply when you select certain patterns or pictures; for example, the INDEX, CYCLE, RANGE, and SIGN parameters are used only with numeric fields. Table 1 shows which IEBDG keywords can be used with which patterns. Each keyword should appear no more than once on any FD statement.
