			The local filenames shown above preserve the source z/OS data set names for clarity. Qualifiers such as <code>TOM</code> and <code>ULSPFTOM</code> are specific to the user or account that owns the source files and will vary for another person running the Online. Substitute the names used for that user's downloaded copies throughout <code>emu204.jsonc</code>. The DD names on the left, such as <code>QAPROC</code>, <code>M204PROC</code>, <code>CCASYS</code>, and <code>CCAGRP</code>, must still match the Model 204 file names expected by the procedures.

	On macOS use <code>/Users/<var>name</var>/m204-81</code> in the two paths. The <code>ccain.txt</code> is below. Each line ending in a dash must have that dash in column 72 (see above):		On macOS use <code>/Users/<var>name</var>/m204-81</code> in the two paths. The <code>ccain.txt</code> is below.
