GoTo
The GoTo instruction is used in conjunction with the Label: instruction to cause program flow
to transfer to a specified location within a program. The destination label is allowed to be
above or below the GoTo instruction within the same program. It is not possible to GoTo a
label outside of the program containing the GoTo instruction, nor is it possible to use a GoTo/
Label: to exit out of a For Count/Next loop. In either of these conditions, a RedDot error will
be generated.

The Label to which program flow transfers is a character string up to 50 characters in length
and can be made up of any alphanumeric character. The label name must not start with a
number, and must end with a colon character “:”.
and can be made up of any alphanumeric character. The label name must not start with a

Labels are not case sensitive.
Example:
Do While (TRUE)
If (DriveInput.1 = ON) Then
GoTo RunIndex1: ‘Go to RunIndex1 label
Else
GoTo RunIndex2: ‘Go to RunIndex2 label
EndIf
RunIndex1:‘ If Input.1 is on, resume here
Index.1.Initiate
GoTo EndLoop: ‘GoTo EndLoop label
RunIndex2:‘ If Input.1 is off, resume here
Index.2.Initiate
EndLoop:
Wait For Index.AnyCommandComplete

Motion Instructions
Dwell For Time
This motion instruction is used to pause program execution for a very precise amount of time.
It operates as a motion instruction – similar to an index, home or jog. Like all other motion
instructions it will not start until the preceding motion instruction has completed. A “Wait for
Index.AnyCommandComplete” is not required. Likewise, any subsequent motion commands
will wait and start after the dwell has completed. The total time required to complete a sequence
of indexes and “Dwell For Time” instructions is extremely repeatable.
