The three (XXX) shown in this manual after an ENTER or OUTPUT
statement represents the device address required by your controller.
Example 1
OUTPUT ON”
In example 1, the colon between SYSTEM and HEADER is necessary
since SYSTEM:HEADER is a compound command. The semicolon
between the HEADER command and the
command is
the
required program message unit separator . The
command does not need SYSTEM preceding it, since the
SYSTEM:HEADER command sets the parser to the SYSTEM node in
the tree.
Example 2
OUTPUT
or
OUTPUT
OUTPUT DESCRIPTION”’
In the first line of example 2, the “subsystem selector” is implied for the
STORE command in the compound command. The STORE command
must be in the same program message as the INITIALIZE command,
since the c program message terminator
will place the parser back at
the root of the command tree.
A second way to send these commands is by placing “MMEMORY:”
before the STORE command as shown in the fourth line of example 2.
Example 3
OUTPUT
AL
L
In example 3, the leading colon before SYSTEM tells the parser to go
back to the root of the command tree. The parser can then see the
SYSTEM:PRINT command.
