- 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.
