Row Numbering

Row numbers in a variable database are initially incremented by 1000.

• When a new row is inserted (by option I or R), it is assigned an intermediate number incremented by 100.
• Rows inserted between row numbers with a hundreds value are assigned numbers incremented by ten.
• Rows inserted between row numbers with a tens value are assigned numbers incremented by one.

For example, a row inserted immediately after row 2000 is assigned a number of 2100.

A maximum of 999 rows may be inserted between two original rows in a variable database.

Row numbers can be refreshed (that is, assigned new numbers incremented by 1000) in the following way:

1. Unload the IOA Variable Database Variables file using job IOAVARUL in the IOA JCL library. This job invokes the IOADUL utility.
2. Reload the file using job IOAVARLD in the IOA JCL library. This job runs the IOADLD utility with the RENUM parameter specified.

For more information about the IOADUL and IOADLD utilities, see the INCONTROL for z/OS Utilities Guide.
