Re: BRMS save failed and ended with a MCH3601

[DrFranken <midrange@xxxxxxxxxxxx>]

Not sure this is directly related here but MCH3601 in my experience is 
often caused by passing incorrect or mis-aligned data to and from 
programs. One example would be passing in a 30 byte string to a program 
expecting a 50 byte string. Or as I had last evening calling an API that 
has an error code return area but I neglected to initialize the field 
that indicated how many error bytes I expected the API to return. Given 
it was not initialized when no tapes were returned (an empty list). The 
API then attempted to hand me a CPFabcd telling me the list was empty 
however instead it threw an MCH3601 which came back to my program.

This is a long way of saying 'It's likely in the BRMS code'. Although is 
it possible there are no tapes available in the library for BRMS to use 
causing exactly the same issue I ran splat into last night?
