Sir, I've been shot for this before so I'll be brief ....
In a manner of speaking, TCBNOIRB vs TCBFX is more about asynchronous vs. synchronous. That said, 'an' aspect is the restriction of IRB's but NOT SRB's, a 2nd would be the 'specific' user. I know SMS is one of them and the other, for quite a while has been JES .. or more specifically, the SYSOUT interface .... yes S/TIRB's are great but doubt that that many will ever need one. A third might, going along the lines of #2 might also be how the logic flows .. (with regard to integrity that is). Essentially the function of both flags were to prevent deadlock's ... at least.. as far as I know and both essentially serve the same function (depending on where in the you are in the food chain). This last point goes back to my previous comment about integrity. Tom forgive me if I am incorrect but I thought that FLG8 was supposed to be used in conjunction with NOIRB ... I could be wrong ... but yes, I do concur that they were GUPI (from a certain point in time). I did think though that the 'usage' for FX was externalized albeit limited to the 'privileged'.
