The operands are used with the XQ command in the following format:
Where the ",1" at the end of the command line indicates a restart; therefore, the existing program
stack will not be removed when the above format executes.
The following example shows an error correction routine which uses the operands.

DMC-1600
Retry failed command (operand contains the location of the failed command)
Skip failed command (operand contains the location of the command after the failed
command)
XQ _ED2 (or _ED3),_ED1,1
FUNCTION
Addition
Subtraction
Multiplication
Begin thread 0 (continuous loop)
End of thread 0
Begin thread 1
Create new variable
Set KP to value of N, an invalid value
Issue invalid command
End of thread 1
Begin command error subroutine
If error is out of range (KP -1)
Set N to a valid number
Retry KP N command
If error is invalid command (TY)
Skip invalid command
End of command error routine
