This term applies to algorithms that are enabled to 
swap. These algorithms can be exchanged with 
another of the same name while the original is 
running. The "new" algorithm becomes active 
after an update command is sent. This "new" 
algorithm may again be swapped with another 
and so on. This capability allows changing 
algorithm operation without stopping and leaving 
this and perhaps other processes without control.

The screw-terminal blocks connected to the 
system field wiring. The terminal blocks are 
inside the Terminal Module.

The plastic encased module which contains the 
terminal blocks connected to the field wiring. The 
Terminal Module then is plugged into the 
VT1422A's front panel. 

This is an intended change to an algorithm, 
algorithm variable or global variable that is 
initiated by one of the commands 
ALG:SCALAR, ALG:ARRAY, ALG:DEFINE, 
ALG:SCAN:RATIO, or ALG:STATE. This 
change or "update" is considered to be pending 
until an update command is received. Several 
updates can be sent to the Update Queue, waiting 
for an update command to cause them to take 
effect synchronously. The update commands are 
ALG:UPDATE and ALG:UPD:CHANNEL.

A list of scalar variable values and/or buffer 
pointer values (for arrays and swapping 
algorithms) that is built in response to updates 
(see Update). When an update command is sent, 
scalar values and pointer values are sent to their 
working locations.

A function callable from the Algorithm Language in 
the general form <function_name>(<expression>). 
These user defined functions provide advanced 
mathematical capability to the Algorithm Language.
