B4P Reference

Function Names

variable save

Description

This function saves the contents of a variable into a JSON file. If the file is already existin, then the contents will be replaced (and not appended).

Since JSON does not support intermediate nodes in the data trees, but B4P variables do, the base variables at all levels will be put into intermediate arrays containing 2 elements. Element 0 contains the value of the base variable, and Element 1 contains further data up the data tree.
