Saving variables to SD card while live

I'm working on a patch that includes saving tables to the SD card using table/save, to be recalled later using table/load. I want also to be able to save certain variables along with the table, such as integers representing loop points in the table. Is there an "official" way to do this? I'm aware of the preset system, but it's not obvious to me how it can be applied here.

For saving table data to sd card you need to use table/write. And then when the data is written to table, you need to save it, by using table/save. And then load it with table/load.

Sorry, I think I wasn't clear -- I already know how to handle saving and loading of tables, but what about saving other variables, such as a single int32?

Oh, sorry, maybe I misunderstood it too

Iirc you can currently only read/write tables conveniently with ready made objects. What i would do is use a table that holds all your single variables, and then you call from that table and save/load it from sd. Worst case use a 2 entry table for single variables.

You can add a objref attribute to any object and then you have access to the referenced table within the object.

Ah, I was afraid that was going to be the solution. Is there a how-to anywhere regarding this objref technique? I don't remember coming across it in any documentation.

Something like this:

Each table read out is set to s specific slot in the table, 0 to 3 to read the data from their specific slot.

That worked, just had to hack the table/write and read objects to use integers rather than fractionals.
