Token Description
ZEMS-TKN-CONTENT-STANDARD Indicates the type of standard event. Value is ZEMS-
VAL-ATTN-NEEDED.
ZEMS-TKN-EMPHASIS Has the value ZSPI-VAL-TRUE for those XIO
subsystem event messages that are potentially
critical. Otherwise, ZEMS-TKN-EMPHASIS always
has the value ZSPI-VAL-FALSE.
ZEMS-TKN-EVENTNUMBER Event number for each ZXIO event message.
