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

• When a new row is inserted, 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 can be inserted between two original rows in a variable database. Row numbers can be refreshed (that is, they can be assigned new numbers incremented by 1000) as follows:

Unload the IOA Variable Database facility’s Variables file by running job IOAVARUL in the IOA JCL library. This job invokes utility IOADUL.

Reload the file by running job IOAVARLD in the IOA JCL library. This job runs utility IOADLD with parameter RENUM specified.

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