One way, not necessarily the most elegant, is to establish an ESTAE or FRR, put your program into key 0, and do an OI into any byte in the page with an operand of X'00'. This instruction will not change the byte being accessed, but if the page is page protected your OI will produce a S0C4 which you trap and from which you recover in your recovery routine. If the page is not page protected, the next instruction after the OI will execute. Bill Fairchild Plainfield, IL
