  • The following table matches the values specified on the IS or IS_NOT parameters with the actual I/O return codes. For more information, refer to I/O Return Codes:

    'VE'

    *ERROR

    'ER'

  • IF_STATUS does NOT check the value of #IO$STS. IF_STATUS simply returns the status of the last database I/O command. In many cases this will be the same as IF COND(#IO$STS *EQ {Some Value}). However it should be noted that in the following cases these statements will be different:

  • When #IO$STS is being set through an Output mapping of a MthRoutine.

  • When #IO$STS is being set through an Output mapping of a SubRoutine.

  • When #IO$STS is being used in the TO_GET parameter of a USE command.

  • When #IO$STS is EXCHANGE'ed from another program/function.
