If having "used the same concept in RPG and it worked great"

not exhibit the same "no permissions" outcome, then that flag is
probably not germane; at least seems improbable unless the openFlag
mismatched betwixt.

The open() API has optional parameters, prototyped in C by "..." and prototyped in RPG by OPTIONS(*NOPASS). Parameters are passed differently when the compiler knows that some of them are optional. For RPG, if you don't code OPTIONS(*NOPASS) on the optional parameters, the API might interpret the optional parameters incorrectly even when they are passed.

I'm just wondering if the other mechanisms to call open() are not able to pass the optional parameters correctly.
