FM-3 Programming Module Reference Manual

Bit And

This operator may be used when it is desireable to AND each individual bit of a 32-bit

parameter.

var.var2 = var.var0 bitand var.var1

For example: if var.var0 = 1000 and var.var1 = -1

var.var0 = 0000000000000000000001111101000b

var.var1 = 1111111111111111111111111111111b

var.var2 = 0000000000000000000001111101000b

Bit Or

This operator may be used when it is desireable to OR each individual bit of a 32-bit

parameter.

var.var2 = var.var0 bitor var.var1

For example: if var.var0 = 1000 and var.var1 = -10000

var.var0 = 0000000000000000000001111101000b

var.var1 = 1111111111111111101100011110000b

var.var2 = 1111111111111111101101111111000b

Label:

The Label: instruction is used in conjunction with the GoTo 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 string of 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 “:”. When using the Label: instruction, a “:” will be

automatically inserted for the user.

Labels are not case sensitive.

Example:

Start:

Index.1.Initiate

Wait For Index.AnyCommandComplete

If (DriveInput.2 = ON) Then

GoTo Start: ‘Go to Start label if Input2 on

EndIf
