Discussion
The DBL$SETKRF subroutine sets the key of reference that the next operation will use. It resets the current position in the file to the first record.
We recommend you use the KEYNUM qualifier on I/O statements instead of the DBL$SETKRF subroutine. |
You can call this routine as SETKRF as long as you don’t compile with the /NOGBLDEFS option. |
