How would I write a script to accomplish the following? If the difference in BPM between the two loaded songs is less than a certain amount (call it X), then play_sync, otherwise play.
The logic is this:
if (difference in BPM between deck 1 and deck 2) < X
then play_sync
else play
The expression in VDJscript might look something like this:
if difference between "deck 1 get loaded_song 'bpm'" and "deck 2 get loaded_song 'bpm'" < X ? play_sync : play
If anyone can figure out exactly how to do this, please let me know.
Thank you!

I don't really understand the scope, I get what you want to do, but not why you'd want to do it. (you can do it manually)
I had a couple of attempts and I can't see a way, if someone else knows I'd be interested.

I don't know the exact syntax but there is a value called get_bpm_match that returns 0.5 if the bpm's are in sync. so the script would be something like:
get_bpm_match = 0.5 ? play : play_sync
if you just want to match bpm without realigning the beatgrid, you could use something like this:
get_bpm_match = 0.5 ? play : match_bpm & play
If you can work out what the values are for the tolerance that you need, you can probably do something like > 0.45 or < 0.55 to achieve the effect for nearby bpm's.
get_bpm_match = 0.5 ? play : play_sync

Thank you, sjlwoods, for your thoughtful reply.
However, I am having an impossible time trying to implement this. First, there are no operators such as = or > or < in VDJscript. The only thing I can find is comparison of variables, such as var_smaller and var_larger. This requires first setting the value of get_bpm_match into a variable then doing the comparison, linking the two commands with "&". I cannot get this to work. Also... even if it did work, it would require something like an absolute-value function before comparing the figures. Ugh.
Again... if anyone can figure out an EXACT syntax for accomplishing this in VDJscript, please advise.

I strongly think it isn't possible, VDJ script can do surprisingly little maths for a scripting language.
If you only wanted pitch 1 == pitch 2 ? sync & play : play,
that would be possible , but you want
pitch 1 => pitch 2 * 0.95 ? pitch 2 =< pitch 2 * 1.05 ? sync & play : play : play
And you just can't do that.
I wish you could, under the hood V8 HAS to be able to do this and I'd have a few applications for it but not possible yet.

Thank you for another thoughtful reply, locodog.
Just to put this into perspective... this programming idea is far from necessary. It would be a nice touch and a good safeguard to add to play_syn... but that's all, definitely not anything that is critical. Was just wondering if it could be done, since I wasn't having much luck. Thanks.

at least that could be done with VDJScript (I think)
get_bpm_match = 0.5 ? play : match_bpm & play
should be either
get_bpm_match param_equal 0.5 ? play : match_bpm & play
or
param_equal get_bpm_match 0.5 ? play : match_bpm & play
get_bpm_match = 0.5 ? play : match_bpm & play
should be either
get_bpm_match param_equal 0.5 ? play : match_bpm & play
or
param_equal get_bpm_match 0.5 ? play : match_bpm & play

Aye like I said testing for exact match is no problem, (There are a few ways it can be done) but to test a unknown number within tolerances can't be done.

How about:
get_bpm_match & param_greater 0.6 ? play : get_bpm_match & param_smaller 0.4 ? play : play_sync
Would that work?
