Jeesh Jon, There's obvious and then there is OBVIOUS <grin>. I didn't miss OBVIOUS. Not to say it couldn't happen but not this time!
Note the pseudo mainline has a comment about calling fclose() which I did verify in debug.
It tells me it's writing 18 bytes and I see the file created. Just nothing in it. Yeah, I may end up using open/read/write instead but now it's a grudge match to get this working.

I know this is too obvious to be the answer but ...
The code sample you show does not close the file. It would be buffered I think using the C routines.
I tried out a quick hack combining your stuff with Simon's code from his RPG blog (I've only ever use the unix-style APIs for this stuff) and I certainly got a whole boat load of data in the IFS. Incomprehensible because I didn't bother to set the code pages etc. but it worked just fine.

Nope. There is an assignment appending the null terminator. I tried that in lieu of using %str() on pText to see if it made a difference.
The write function is returning 18 so it appears to have written the data but, again, the file is empty.

Just looking at the code, the procedure is getting the data passed into the variable pText, while the function is writing wkText and the incoming data is not being set into wkText.

Subject: fputs() in RPGLE
I am having a brain freeze on using fputs() in an RPGLE program. It needs to be in old-style /free format for another user.
I have this and it is showing 18 bytes written (retBytes) but the IFS file (in /tmp) is zero bytes - checked with Windows Explorer and wrklnk.
I must be missing something very obvious. Thanks.
// call proc to call _C_IFS_fopen mode 'w'
TextData = 'One Line Of Data' ;
TextBytes = IFS_Write(TextData : TextFileHandle);
// invoke proc to call _C_IFS_fclose
