controls whether ter-minal or not
issues the CP accounting information is displayed at the (ON and OFF, respectively) when the operator ACNT command. When you log on VM/370, ACNT is
set on. AUTOPOLL {g;F} MSG {ON } OFF SMSG WNG {ON .} OFF TMSG controls whether or not cp tests each BTAM autopoll C:W to see if it has been dynamically modified. ON indicates that (1) CP testing, and (2) the VS1 operating system is to
notify CP, via the DIAGNOSE instruction code X'0028', after an crw has been modified. ON substantially reduces the over-head required by CP to service BTAM autopoll channel pr-oqrams. OFF causes CP to check each autopoll C:W after each
execution of the channel program and is the default status
when the user logs on. NQtg: T¥ you SET AUTOPOLL ON and the virtual operating system does not have the appropriate Diagnose interface, :P does not
detect chanqes to BTAM channel programs and unpredictabie
results can occur. OS/VS 1 Release 6.0, however, does have
this interface.
controls whether messages sent by the MSG command from other user-s ar-e to be received at the terminal. If ON is specified,
the messages are displayed. If OFF is specified, no messages ar-e received. In addition to controlling messages generated bV the MESSAGE command, spooling messages generated by users
sending punch, printer or reader files to another virtual
machine are also suppressed if OFF is specified. When you log
on VM/370, is set on. whether a virtual machine is rece1v1ng special
messages or not. If OFF is specified, the virtual machine
cannot receive special msssages.
controls whether warning messages are displayed at the terminal. I¥ ON is specified, all warning messages sent via
the CP WARNING command from the system operator are received
at the terminal. If OFF is specified, no warning messages are r-eceived. When you log on VM/370, WNG is set on.
controls whether certain informational responses issued by the CP CHANGE, DEFINE, DETACH, IPL, ORDER, PURGE, and TRANSFER commands are displayed at the terminal or not. The
descriptions of these CP commands tell which responses are affected. If ON is specified the informational responses are If OFF is specified, they are not. The SET IMSG ON or OFF command line has no effect on the handling of error
messaqes set by the SET EMSG command. When you log on VM/370, IMSG is set on. 130 IBM VM/370 CP Command Reference for General Users
