4.11.4 CM Journal Access Return
The data returned from the Journal Manager surrogate subroutine is a journal reply message
recored followed by the converted ASCII events. Each of the events that are returned from
the Journal Manager have been expanded by the surrogate into 140 character strings. The
CG/PLNM strips off the last 8 characters and places the ASCII time/date information into a
separate field within the same record. The CG/PLNM sends the ASCII events across the
link to the CM50 through the VAX/CG/PLNM reply message.
