_ED2
Retry failed command (operand contains the location of the failed command)
_ED3
Skip failed command (operand contains the location of the command after the failed
command)
The operands are used with the XQ command in the following format:
XQ _ED2 (or _ED3),_ED1,1
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.
