Re: Opening the same file twice in the same program?

Given your description, this should not present any problems - just define the file twice.

Personally, I avoid the cycle like the plague in part because most current RPGers don't understand it and I like to leave code behind me that any decent RPGer can handle. In your case, frankly, I don't see that it offers any benefits. Perhaps even more importantly the cycle can't be used in free-form RPG and that is all I code.

While the initial usage of the program may not give rise to any scatter-gather conflicts I would still program to avoid them for maintainability. Either by using a prefix on one of the files or by using DS I/O which would be my preferred approach in a case like this.

Suppose I want to have two cursors (one as a primary file, read only; the other as a full procedural file, read/write) on the same file.

And the situation is such that there's no problem with scatter-gather using the same field names.

The idea is that the program is going to ride The Cycle through the file. After every 1000 records, it's going to process those records, and then go back through the records it's just read, and plug values into several fields on those records.

I could of course use a logical for one of them, but I vaguely recall seeing something fairly recently, about a way to just open the same file twice.

Can anybody refer me to what I might have seen?
