How to pass constant string into a genSub or sub record

[Susanna Jacobson <SRJacobson@lbl.gov>]

Hi folks,

This concerns subroutine and genSub records in EPICS R3.13.4.

I need to pass a string into a subroutine or general subroutine
record at initialization time because I don't want to fix the information
in the code for the record's init and process routines.
So I assigned the string to an input link in the .db file, just as one 
would pass a numeric constant.  However, the record interprets the string 
as a PV name, which generates a lot of pointless network traffic as link 
processing looks for a record with that name.  

Is there a way to tell the record that the string is a constant and
not a PV name?  Do I have to use a string record to hold the string
and use the input link as a link?  Or is there another, better way to 
do it?

	Thanks in advance,
	Susanna
