I resolved my problem by putting // in front of dd: in the fopen command. I found this syntax at a dovetail site which was discussing BPX... routines.

My application opens several CMS= output files using fopen with a dd name and a corresponding FILEDEF, for = example fopen( dd:OBNLOG, w,recfm=vba,lrecl=125 ) and FILEDEF OBNLOG = DISK OBNLOG LISTING A. The first fopen is successful, but the second (and also= the third) fails with errno=129 errno2=000836. The symbolic for 129 = is ENOENT. No error occurs if I remove the run-time option, POSIX(ON). I need to ha= ve POSIX(ON) because the application uses ThreadCreate and TCP/IP OE sockets= . In searching through the VM documentation, it appears that the dd name is= not correctly resolved by the second fopen. I suspect that it is trying = to access a BFS file. It seems strange to me that the 2nd invocation is different from the first. Any ideas about accessing CMS files in the POSIX environment? I'd appreciate any clues you might have. Thanks for your help, Julie Erickson.
