ILE RPG Language Reference
You define an array on a definition specification. Here are the
essential specifications for all arrays:
- Specify the array name in positions 7 through 21
- Specify the number of entries in the array using the DIM keyword
- Specify length, data format, and decimal positions as you would
any scalar fields. You may specify explicit From- and To-position
entries (if defining a subfield), or an explicit Length-entry; or
you may define the array attributes using the LIKE keyword; or the
attributes may be specified elsewhere in the program.
- If you need to specify a sort sequence, use the ASCEND or DESCEND
keywords.
Figure 68 shows an example of the essential array
specifications.
