Right. I've had more than one occasion to use runtime calls more idiomatic to C, but here, I was looking for something that was RPG-native and RPG-idiomatic.

And Scott said:

I mean... yes you can do this, but... if the only reason is to
clear the file, wouldn't it be easier to just run CLRPFM prior to
opening it?

I quite agree. In this case, lacking a native equivalent, it would probably be easier to make the file USROPN, and wipe the file by shelling out a CLRPFM with QCMDEXC, than to use the _Rxxxxx calls.
