FUNCTION: End
DESCRIPTION:
The EN command is used to designate the end of a program or subroutine. If a subroutine
was called by the JS command, the EN command ends the subroutine and returns
program flow to the point just after the JS command.
The EN command is used to end the automatic subroutines #MCTIME, #CMDERR, and
#COMINT. When the EN command is used to terminate the #COMINT communications
interrupt subroutine, there are two arguments; the first determines whether trippoints will
be restored upon completion of the subroutine and the second determines whether the
communication interrupt will be re-enabled.
ARGUMENTS: EN m, n where
m = 0:
Return from subroutine without restoring trippoint
m = 1:
Return from subroutine and restore trippoint
n = 0:
Return from #COMINT without restoring interrupt
n = 1:
Return from communications interrupt #COMINT and restore interrupt
Note1: The default values for the arguments are 0. For example EN,1 and EN0,1 have the
same effect.
Note2: The arguments will specify how the #COMINT routine handles trippoints. Trippoints
cause a program to wait for a particular event. The AM command, for example, waits for
motion on all axes to complete. If the #COMINT subroutine is executed due to a
communication interrupt while the program is waiting for a trippoint, the #COMINT can
end and continue to wait for the trippoint, or clear the trippoint and continue executing
the program at the command just after the trippoint.
Note3: Use the RE command to return from the interrupt handling subroutines #LIMSWI
and #POSERR. Use the RI command to return from the #ININT subroutine.

EXAMPLES:
#A Program
A
PR 500
Move A axis forward 500 counts
BGA Begin
motion
AMA
Pause the program until the A axis completes the motion
EN
End of Program
Note: Instead of EN, use the RE command to end the error subroutine and limit subroutine. Use the
RI command to end the input interrupt subroutine
