Thanks, night cub.

I'll go ahead and contribute as 6 episode for this season as it is listed in imcdb.org there.

https://en.wikipedia.org/wiki/List_of_Emergency!_episodes#Television_films_(1978–- 79)

Looks like a mistake on IMDB, they usually don't follow the syndicated ep numbers. And it's so strange that it's just the first 3 eps that are split and not the other 3 (which is just 2 eps of new material, it seems)

There are two different version of these episode of 7th season on Emergency! There are the 2-hour version episodes and 1-hour version episodes in that season. I have 2-hour version on DVD and I will be marking different episode listed in parallel with IMDb's listing.

I'll mark them accordingly as I progressed with these 7th season as I update/upload these pictures at imcdb.org. So far, I found at least three 2-hour version listed in this season.

IMDb listed them 1-hour version at: https://www.imdb.com/title/tt0068067/episodes?season=7&ref_=tt_eps_sn_7

Let me know if you have further question about this season episode listing.
