Array Output

Entire arrays can be written out under ILE RPG control only at end of program when the LR indicator is on. To indicate that an entire array is to be written out, specify the name of the output file with the TOFILE keyword on the definition specifications. This file must be described as a sequentially organized output or combined file in the file description specifications. If the file is a combined file and is externally described as a physical file, the information in the array at the end of the program replaces the information read into the array at the start of the program. Logical files may give unpredictable results.

If an entire array is to be written to an output record (using output specifications), describe the array along with any other fields for the record:

• Positions 30 through 43 of the output specifications must contain the array name used in the definition specifications.
• Positions 47 through 51 of the output specifications must contain the record position where the last element of the array is to end. If an edit code is specified, the end position must include blank positions and any extensions due to the edit code (see “Editing Entire Arrays” listed next in this chapter).

Output indicators (positions 21 through 29) can be specified. Zero suppress (position 44), blank-after (position 45), and data format (position 52) entries pertain to every element in the array.
