Daryl,

A quick work around is to define a parameter (such as HGXX) in
$GEMTBL/parms/pcconv.tbl like:

HGXX = PR_M100 ( HG )

Now in sflist:
 SFFILE   = 20010906_test.gem
 AREA     = @cohn6
 DATTIM   = all
 SFPARM   = hg;hgxx
 OUTPUT   = T
 IDNTYP   = STID
 GEMPAK-SFLIST>r
 PARM = HG  ;HGXX                                                               
 

    STN    YYMMDD/HHMM      HG       HGXX
  COHN6    010906/1700      6.04   604.00
