Deferred Commands, Order of Execution
The immediate commands take effect immediately when they are interpreted. Even so, they must be
followed by an Execute (
X
) command to terminate the command string for correct operation. For
example:
K00001X
Deferred commands are not executed until the
X
command has been successfully parsed and
interpreted. Upon interpretation of the
X
command, the order of execution of all deferred commands is
as follows:

take place before any data is acquired.
