FSEDIT screen "Y/N" Input

[Jumboshrimps]

Added a new field to an existing FSEDIT frame.

The only responses are "Y/N".  The variable capturing this response is a 1 char.

How do I restrict responses to  just "Y/N"?

Is it done via code in the SCL, or by limiting the responses in the variable itself, like in other databases?

THX.

It is your choice.  SAS does allow "integrity constraints" to be defined on a dataset (although it did not when PROC FSEDIT was first introduced.)

In my opinion if you are going to the trouble of making an FSEDIT screen then put the logic there.  Trying to use constraints on the actual variables is just going to make working with the data much harder for not much gain.

I see your point.

There is a format library with a $YES/NO format.  I'll try that for now, and see if any complains.
