<p class="MsoNormal">Hi Kit. I'm curious about the support for Clang on z/OS and, in particular, support for EBCDIC based source files and run-time interaction with the OS. Would you be able to describe what features IBM has added (or will be adding) along
those lines? Will the <a href="https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.bpxb200/uenha.htm">
z/OS enhanced ASCII functionality</a> be supported? How about <a href="https://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.cbcux01/ascii.htm">
xlC's enhanced ASCII</a> support? Or <span style="font-family:"Courier New""><a href="https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.cbcpx01/fltg.htm">#pragma filetag</a></span>? Or
