What I was thinking of was this:
gisrate chnget "Samplerate"
sr = gisrate
where "Samplerate" is a value generated by a Lettuce widget prior to running
Csound, probably by a combobox.

If this is not possible, I can handle the issue by passing a macro value via
 or the command line (e.g, sr = $SRATE). Of course, as Rory
indicates, being able to use chnget with widgets would be much nicer. (As
mentioned in an earlier email, I hope to use *massign* with a chnget widget
value in the header also.)
