Another way to check if file exists in IFS

In June I wrote about how to use SQL to check if a file existed in the IFS. I received a communication from Rich Diedrich offering an alternative, using the access C procedure. I have taken his code and developed it into this example.

I created an external procedure that I made into a service program to perform the checking, and then wrote a small RPG program to call it to validate if certain files exist.

I am going to start by showing the source code for the external procedure, which resides in a module I called TESTMOD1.

September's presentations

I am involved with two user group events this month

On Wednesday 3 September I will be in Oslo, Norway, presenting at COMMON Norge's "Professional day IBM Power and AI".

I will be making three presentations in the afternoon. If you are in Norway this will be the event of the year, so don't miss it.

Details of the meeting, and the form to register, is here.

Jeg håper å se deg der!

On my return home, to Austin Texas, I will be hosting the September meeting of the Central Texas IBM i User Group, CTXiUG, on Tuesday September 9 at 6:30 PM CT.

Our guest speaker is my System i Developer colleague Mike Pavlak. He will be sharing his experiences using stored procedures for hybrid devlopment.

The meeting is online and free, and you can learn all about it and register here.
