I have been watching this thread, as have found it interesting. And Yes I agree with others that the OP should use DSECTS/LABELS instead of hard coded displacements. . The Original Post stated they were trying to branch to the address in ECVTXTSW. . > L R15,16 GET CVT ADDRESS > L R15,X'8C'(R15) GET ECVT ADDRESS > L R15,X'384'(R15) GET ECVTXTSW ADDRESS . I looked at the IHAECVT to see the explanation of ECVTXTSW. The comments state "Address of "Cross-memory TCB or SRB wait" routine. . AM I to understand that this routine can be called from an SRB Routine or a Cross Memory PC Service routine to place the SRB routine in a wait-suspend for x-amount of time ? . Is there any additional documentation on this function ? . Is this a restricted function meaning it should not be used because it is undocumented ? . Paul . .
