skip and ask if

[Jing Liu]

Hi,

I am testing the 7.0 now. there is a new command ask if available as an inversion of the skip statement.

if I understand it right, ask if is not as silent as skip or advance. It will pop up whenever the condition meets, even if I am modifying an complete case (given the condition does not control if the field is not entered or not).

May I ask if there is any special situation that I shall use ask if rather than skip or advance?

best

Ask if is a convenient way to skip a field. You could accomplish the same thing with a skip but in many situations ask if is easier to use and makes the code easier to understand. We have found that often the way a questionnaire specification is written is to provide a positive condition - ask the question for all people where a condition is true. This translates directly to ask if but requires negation for skip. Also note that with ask if you don't give a target for the skip. It automatically skips to whatever the next field is.

Ask if behaves like a skip, not an advance, in that in system control mode the question is marked as skipped. With advance the question is marked as answered.

I'm not sure what you mean by ask if not being "silent". The behavior should be the same as with skip.
