Items Stacked by WAKEUP

The seven WAKEUP options that cause data to be stacked are: EXT, FILE, IO, IUCVMSG, SMSG, TIME, and VMCF. WAKEUP stacks the data in the following order regardless of the order the options are specified when you invoke WAKEUP:

  1. Current date and time
  2. Line from the WAKEUP Times file, or an asterisk (*) if no line is found
  3. An IUCV, SMSG or VMCF message, or EXT or IO interrupt data.
Note: In general, the last line stacked by WAKEUP is the one you really want to use, not the first line.
