DBL$SETKRF

Set the key of reference for the next operation on an ISAM file

 

 
VSupported on OpenVMS

 

 
xcall DBL$SETKRF(channel, key_number)

Arguments

channel

The channel on which the files are open. (n)

key_number

The key of reference for the next operation: (n)

0 = Primary key

1 – 7 = Alternate keys

Discussion

The DBL$SETKRF subroutine sets the key of reference that the next operation will use. It resets the current position in the file to the first record.

Tip

We recommend you use the KEYNUM qualifier on I/O statements instead of the DBL$SETKRF subroutine.

Note

You can call this routine as SETKRF as long as you don’t compile with the /NOGBLDEFS option.
