Assume that the answer to the continue fitting question is no.
XSPEC> query no
The continue fitting question in fit, steppar, and error will not be asked when the number of trials is exceeded. Also, when the number of trials to find the error is exceeded, a question will not be asked. In both cases the program will behave as if a no answer was given to the question, that is, it will stop and return to the XSPEC prompt.
