Expected output for edit routines
The edit routines return different output depending on whether the input row is in the coded or decoded form.
If
EDITCODE contains 0, the input row is in decoded form. Your routine
must encode it. - In that case, the maximum length of the output area,
in EDITOLTH, is 10 bytes more than the maximum length of the record.
In counting the maximum length for a row in basic row format,
record
includes fields for the lengths of varying-length columns and for null indicators. In counting the maximum length for a row in reordered row format,record
includes fields for the offsets to the varying length columns and for null indicators. The maximum length of the record does not include the 6-byte record header.
If EDITCODE contains 4, the input row is in coded
form. Your routine must decode it.
- In that case, EDITOLTH contains the maximum length
of the record. In counting the maximum length for a row in basic row
format,
record
includes fields for the lengths of varying length columns and for null indicators. In counting the maximum length for a row in reordered row format,record
includes fields for the offsets to the varying-length columns and for null indicators. The maximum length of the record does not include the 6-byte record header.
In either case, put the result in the output area, pointed to by EDITOPTR, and put the length of your result in EDITOLTH. The length of your result must not be greater than the length of the output area, as given in EDITOLTH on invocation, and your routine must not modify storage beyond the end of the output area.
Required return code: Your routine must
also leave a return code in EXPLRC1 with the following meanings:
If the function fails, the routine might also leave a reason
code in EXPLRC2. Db2 returns
SQLCODE -652 (SQLSTATE '23506') to the application program and puts
the reason code in field SQLERRD(6) of the SQL communication area
(SQLCA). 
| Value | Meaning |
|---|---|
| 0 | Function performed successfully. |
| Nonzero | Function failed. |
