The [R] command tells the pump to execute a previously sent command or program
string.
Commands containing an [R] at the end of the string will execute immediately. If the
command or program string is sent without the [R], it is placed in the command buffer.
Sending the [R] alone will execute the last unexecuted command in the buffer. Sending
another [R] will not repeat the program string (i.e., the string has been executed).
NOTE The [R] command is invalid in CAN communication. The equivalent
command is ASCII 1 for frame type 2.

TRING
The [X] command repeats the last executed command or program string.
NOTE The [X] command is invalid in CAN communication. The equivalent
command is ASCII 3 for frame type 2.

OMMAND
S
EQUENCE
The [G] command repeats a command or program string the specified number of times. If
a GR or G0R is sent, the sequence is repeated endlessly until a Terminate command [T]
is issued. The syntax for this command is:
[G<n>], where <n> = 0..30000
For example:
[A3000A0G10R] moves the syringe plunger to position 3000 then back to position
0. This sequence is repeated 10 times.

EQUENCE
The [g] command is used in conjunction with the [G] command. The [g] command marks
the beginning of a repeat sequence (loop) that occurs within a program string (i.e., the
entire string is not repeated). Both the [g] and [G] commands can be used to nest up to 10
loops.
Table 3-5 shows the various segments of the command string
[A0gP50gP100D100G10G5R].
