2.7.3 LDAT, Review of Messages by Date
Operation LDAT provides a review of the number of messages in the circular buffer. The
subtotals are arranged according to date and a grand total is given at the end of the
summary.
The CMB can also store data blocks specific to output devices and programs. Such
entries cannot be directly accessed by a user but are summarised at the end of a
"LDAT" listing. The entries are divided into four types:
–
Reaction Macros
All Macro statements concerning Reaction programs.
–
Empty CMB Buffers
A counter shows how many buffer locations are free. Once the CMB is full, the pointer
always indicates zero. Then, because it is a circular buffer, there cannot be any free
locations left.
As in Operation LIST, messages may also be selected according to the following
criteria:
–
Time Interval
