[EmData] Alternating Greybar question

[Radford Parsons]

I am producing an employment advertisement, comprised of liners and
columns--a perfect construct for InData. I have set the prototype to
create a six-field, horizontal grid, separated by headlines.

Here is my question: Is is possible to set (within the data, for
instance) a "field-independent" command that will create an alternating
greybar listing (for readibility)? I have not been able to find a
prototype command that will create this effect without duplicating the
listing, other than to add an additional "empty/not empty" field. I've
attempted an «if/else» statement but the effect is the same:
duplication. The database from which I'm drawing is restricted to a
six-field grid.

Has anyone encountered/overcome this InData challenge?

Thank you.
