EXTIND(*INUx)

The EXTIND keyword indicates whether the file is used in the program depending on the value of the external indicator.

EXTIND lets the programmer control the operation of input, output, update, and combined files at run time. If the specified indicator is on at program initialization, the file is opened. If the indicator is not on, the file is not opened and is ignored during processing. The *INU1 through *INU8 indicators can be set as follows:

• By the IBM i control language.
• When used as a resulting indicator for a calculation operation or as field indicators on the input specifications. Setting the *INU1 through *INU8 indicators in this manner has no effect on file conditioning.
