RE: EOF

i agree that is the best method, but the code as presented *will* work
(unless the other scenarios presented by others get inserted into the
equation)


Thanks,

My vote is use the qualified %eof.
Don't forget a program change can be tested, but a particular faulty logic
situation may not be found until AFTER its in production

Come on, guys it only becomes toast if you modify it AND don't test it!

Noone answered the second part, are there several levels of EOF? Ie one
for
each file and one for the last file read?

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.

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
