Not that I know of.  Since the ability to plot partially filled circles
exists (used in SFCMG), this should not be too hard to add to SFCPLOT.

I am suprised that my builds on OSF/1 5.1 didn't find this.  When we were
running OSF/1 4.x, our Fortran compiler always complained about things like
this, and I made a number of code modifications to get around the problem.

Try changing "type=char(0)" to "type=' '"; recompiling; and rerunning your
test.  Your change may be causing this since the length of the character
string will be non-zero, and the code then appends the value of 'type'
onto the parameter definition:

c --- check for the parameter type (CHILLTYPE) keyword
      status = mccmdstr('CHI.LLTYPE',1,' ',type)
      if( status.lt.0 ) return
      call mcupcase( type )
      if (type(1:3) .eq. 'CUR' .or. type(1:3) .eq. 'NEW' .or.
     &    type .eq. ' ') then
           type = ' '                   ! <<<<< UPC mod 20020522 OSF/1 4.0 mod
      elseif (type(1:3) .eq. 'OLD') then
           type = 'OLD'
           call edest
     &         ('Valid entries with CHILLTYPE are CURRENT and OLD',0)
      len_type = len_trim( type )
      if( len_type.gt.0 ) then
         len = len_trim( parameter )
         parameter = parameter(1:len)//'.'//type(1:len_type)

Setting type to ' ' (one space instead of no spaces) should satisfy your
compiler and result in a len_type of zero.

Tom and Randy,

I made the change as suggested and rebuilt and reinstalled McIdas.
Mary Ellen checked it out and it does work now.

Tom, FYI, the compile problem didn't occur on our Tru64 Unix 5.1 build,
but it is running a newer version of the Compaq Fortran.

Thanks for your help, Tom.
