Thanks for the information. I'll try updating my directory entry and see if that's sufficient to give my access to OpenExtensions.
Here's some information about errno 167. I looked up 167 in errno.h. Here's the entry: #define EMVSNORTL 167 /* Access to the USS version of the C RTL is denied */ When I searched on EMVSNORTL in the online VM doc, I found the following in the LE Debug & Messages doc: EDC5167I Access to the OpenEdition MVS or OpenEdition VM version of the C RTL is denied. Explanation: An attempt was made to issue an Open C library function that has a dependency on OpenEdition MVS or OpenEdition VM and the subsystem w as not available or at the incorrect release level. This message is equivale nt to the OpenEdition errno, EMVSNORTL. Programmer Response: You need to either install the correct level of the subsystem or modify your program to not issue the function or conditional ly issue the function. If you received this message and you are not running under OpenEdition, make sure that POSIX(ON) is set. System Action: The request fails. The application continues to run.
