EXEC_SPF

Is anyone have success using the new 8.4 EXEC_SPF function?

It does seems that EXEC_SPF can only use Stored Procedures with an OUT parameter of type DOUBLE or INTEGER (ie you cannot return VARCHAR/TEXT)?

I was also hoping to call it inside <<Tokens>> to include the OUT value in AwareIM VPs and forms but

<<EXEC_SPF('StoredProcedureName','MAIN',Object.ID)>>

does not seem to work.

I am using it in a few places and I have not had a need to return a varchar yet.

I like the functionality it offers in rules.
