If the sentence 'done' is false after execution, how will subsequent TdEntries be executed #248

However, there are still many TdEntry ->nextSteps in iv_queue that have not been executed. I guess there should be some way to continue executing TdEntry in iv_queue after iv_curProcedure is completed. Can you give me a rough description of where iv_queue [i]. nextStep() was executed Thanks!

If 'done' is false, the current procedure has not yet finished and as such will not move onto the next procedure in 'iv_queue'. In that case, another MCBIST command is expected to have been triggered and there will be a subsequent command complete attention where 'nextStep' will end up called again.
