Quote from http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CBCPG1C0/2.9.1.1.1 "When you enclose a name in single quotation marks, the name is fully qualified. The file opened is the one specified by the name inside the quotation marks. If the name is not fully qualified, z/OS XL C/C++ does one of the following: - If your system does not use RACF, z/OS XL C/C++ does not add a high-level qualifier to the name you specified. - If you are running under TSO (batch or interactive), z/OS XL C/C++ appends the TSO user prefix to the front of the name. For example, the statement fopen("a.b","w"); opens a data set tsoid.A.B, where tsoid is the user prefix. If the name is fully qualified, z/OS XL C/C++ does not append a user prefix. You can set the user prefix by using the TSO PROFILE command with the PREFIX parameter. - If you are running under z/OS batch or IMS (batch or online), z/OS XL C/C++ appends the RACF user ID to the front of the name."
