Subject: keyword with multiple values

What is the recommended keyword approach for describing
a parameter with several  (say < 100) values?  Assume a FITS file is 
generated from a program run with PARMS=(1.1, 2.2, 3.3).  One approach would
be FITS keywords of the form PARMS1=1.1, PARMS2=2.2, etc.,
similar to the NAXIS usage.   I've seen mention of hierarchical keywords,
but I gather that is discouraged.   Are there other approaches?
