And if someone adds an exsr after the read, and there is file
i/o in that subroutine, you're toast...

This will work today, but as someone pointed out, as soon

as someone

adds another I/O, the routine becomes toast.

I prefer to use my own indicator. This will produce a considerably
more stable application. See the semi-pseudo code:

DoU noMoreRecords ;
Select ;
When cond1 ;
Read file1 ;
noMoreRecords = %EOF(file1) ;
when cond2 ;</snip>

not true. if the new I/O is just adding a new file in a WHEN
condition it will still work as designed without a problem.


Thanks,

Will the test on EOF work correctly ? Will it be on if

either of the

3

files is at condition %EOF ? Do I need to check EOF for each file?

Does an indicator EOF exist for all 3 files plus another that

indicates

any of the files?

Thanks!

Select
when cond1;
read file1;

when cond1;
read file2;

etc
other;
read file3;

EndSl;

IF %EOF;
etc
