GETTAB TABLES
23.3 ADDING ITEMS TO THE MONITOR'S GETTAB TABLES
System programmers can add words (items) to the monitor's GETTAB
tables. The items added must have negative indexes, and must be added
at the top of the table in the order -n, -(n-1), -(n-2), ... -2, -1.
When the monitor is assembled, the range of valid indexes for each
table must begin with the lowest (most negative) index, and proceed to
the highest index.
It is good programming practice to use a .UNV file containing symbols
for these items for use in programs. This usage is similar to that of
searching UUOSYM.UNV.
23.4 ADDING NEW GETTAB TABLES TO THE MONITOR
System programmers can add completely new GETTAB tables to the
monitor. These tables must have negative table numbers, and must be
added at the beginning of COMMON.MAC in the order -n, -(n-1), -(n-2),
... -2, -1. When the monitor is assembled, the range of valid table
numbers must begin with the lowest (most negative) table number, and
proceed to the highest table number. within these added tables, items
must be indexed sequentially.
For example, the system programmer can add a new table with the number
-1. This table must be added to the source code in the monitor module
UUOCON. The items in this table could begin and end with negative
indexes; for example, the indexes could begin with -14 and end with
-1. The items could begin with a negative index and end with a
positive index; for example, the indexes could begin with -10 and end
with 27. Or the items could begin and end with nonnegative indexes;
for example the indexes could begin with 0 and end with 15.
