Turn a TYPE variable into a JSON string. Keys are the member names. Integers have no decimal. The result grows as needed (a hard internal cap raises ?OVERFLOW). JSON$ can query the result.
JSON_STRINGIFY$(var)
var - TYPE variable
Returns the JSON text as a string.
Example:
s$ = JSON_STRINGIFY$(w)
PRINT JSON$(s$, "temp")
