According to a PMR response from 2009, the previous support team have said that SuperC has never officially supported tape input or output files on z/OS, although this still needed to be documented as a restriction. (The current team have not seen any clarification of the reasons, and some cases certainly work anyway, but it appears that some data management functions used by SuperC may be ignored for tape, causing the job to hang).
As the Large Block Interface support for blocks exceeding 32760 bytes is only needed for tape I/O, there would be no point in implementing support unless we could also solve the other limitations of tape support, which have previously been considered a permanent restriction.
We are therefore declining this request.
