Issue/Introduction

In the TSSCFILE Utility Guide, the layout of Record Type 2005 is shown as follows:
========================
33 40 8 XAUTH Resource Class Name
41 48 8 XAUTH Owner ACID
49 56 8 XAUTH Until Date
57 100 63 XAUTH Resource
========================

At first, it appears that the numeric columns correspond to starting position, ending position, and length, respectively. However, this doesn't work for the
last specification, for which 57-100 corresponds to a maximum of 44 bytes. In addition, there is no indication of how a long Resource ID is to be handled.



Please provide an explanation as to the Record layout for Resource Classes having MAXPERMIT(...) settings up to 255 characters?

Environment

z/OS and Top Secret r15.0 and r16.0.

Resolution

The documentation for CFILE Record Type 2005 is misleading. Since it can handle a Resource Permit up to 255 characters, the last line of the entry should look like this:
57 300 255 XAUTH RESOURCE (continued on next record if needed)

The value '300' represents the maximum Record Size for a CFILE Record. So on a single Record we can represent a Resource Permission with a length up to
244 characters. If the PERMIT is greater than 244 characters, then CFILE will generate a continuation Record for the remainder of the data, and the initial Record will be marked with a 'C' in column 12, as documented in the CFILE Record Format description.
