and the command is executed without error.
The command 'LEV' has only one node, therefore the current base
node is not changed.
rn
'OFFS' is found under the current base node ':VOLT7 (the optional
nodes 'LEV' and 'IMM' have been skipped), the parameter
'0.5'
is
parsed and the command is executed without error.
The command 'OFFS' has only one node, therefore the current
base node is not changed.
rn
The colon
0:')
prepending 'ABOR' is seen.
b
<root> is the new
current base node,
rn
'ABOR' is found under the current base node <root>, the
command takes no arguments and executes without error.
The command 'ABOR' has only one node, therefore the current
base node is not changed.
rn
The program message terminator ('<CR/LF>') is seen.
b
<root>
is the new current base node.
One final note:
The term 'command executes' means that the command is executed
from the point of view of the parser.
If
You look at it as an
instrument user, you should refer to the section "Value coupling" in
chapter
4
for more information about command execution.
