Yes. Bit 17 of the result area of the STFLE (Store Facility List Extended) instruction is set to one (1) when the Message Security Assist (i.e., CPACF) is available.
In addition, bit 76 is set to one (1) when the Message Security Assist Extension 3 is available, and bit 77 is set to one (1) when the Message Security Assist Extension 4 is available. You can then use the query function of each of the various CPACF-supplied instructions to determine the availability of more granular capabilities. John P.
