stringin/out <-> sub record ?

["Laznovsky, Michael" <lazmo@slac.stanford.edu>]

Hi- how can I get strings in & out of subroutine records?

It appears that the sub record tries to convert all its inputs 
to "double" before calling the user function, and complains if it 
fails.  All I want is to read/write actual strings from inside 
the function.

thanks, 
Mike
