Is it possible to write a NOWAIT I-O in HP NonStop COBOL?

I have a task to write a program to generate three “reports” [CSV files to be downloaded to a desktop for use in EXCEL]. I think I have one of four ways to do this.

1. Run the program three times with different input
2. Call subroutines each of which will produce a different CSV file.
3. Run the program once, build on O/P file; and then, SORT the output into three different CSV files. or
4. Run a requester and three servers [non Pathway] with each of the servers generating a report.

If I choose option 4, I want to speed up the processing by doing a NOWAIT I-O in the requester. I don’t want to use an ENTER TAL construct and use a Guardian I-O if I can avoid it. My TAL is rusty; and, I am working in a COBOL shop.

I want to know if I can issue a NOWAIT I-O WRITE from the requester to each of the servers and then execute an AWAITIO.

Is this doable; or if I solely use COBOL, am I stuck using WAITed I-O?

Thanks.

I haven’t tried anything yet; I have just now sat down to plan and write this program.
