They do indeed. The CA products (the only RACF competitors I am aware of), set the RCVT eye catcher at +0 to "ACF2" and "RTSS" respectively. In general the most commonly used programming interface fields in the RCVT are set correctly or at least usefully by the CA products. So for example the flag indicating that mixed case passwords are supported is present on all systems. As for the release, the fields RCVTVRMN and RCVTVERS are kept meaningful in terms of what features are supported on all three systems, but if you want to know the actual installed version of the CA products, you probably have to look at their own control blocks. For TSS, there is an extension way beyond the IBM-defined length of the RCVT. For ACF2, there is a separate control block reachable using the fairly comprehensive ACF2 documentation, that I think holds the information you need. Tony H.
