You could keep all your 'global' variables in a structure or two and declare
them in the common block.  Using structures to group related variables together
is good practice anyway.  I tend to keep all the varaibles dealing with a set
of widgets and their contents etc in one structure.

Someone suggested another method in this newsgroup a month or two ago, whereby
you can use the UVALUE for the widgets to pass information around.  This was
for IDL, but I imagine it would work for PV-Wave.

We are getting several Sun Sparc 10 servers.  We have the option of getting Solaris 2.1 or SunOS4.1.3.

Does anyone have any experience running IDL under Solaris 2.1 ?

Is there a version of IDL for Solaris or will the current Sun release work under the
binary compatibility mode ?

	you can't do it directly.  what i do is interpolate
my polar grid to a cartesian grid and then contour it.  i use
trigrid and triangulate to do the interpolation.
	the problem i still have is that polycontour bites.
if anyone has a color contouring routine which knows how

What I've done is use Map_Set using a polar
stereographic projection and then contouring some
data on top of it.  In the following example
`matrix1' is a 380 x 15 floating array consisting
of monthly measured heat fluxes at latitudes 50 to
85 deg. N.  (see Oort).  My data is available on
request.  If you just want to try this out, create
an array that varies from about -400 to +400 or so:

   restore,'fwall_matrix.dat'
   x = seqa(-180,30,13)
   y = seqa(50.,2.5,15)
   xx = [min(x),x,max(x)]
   yy = [min(y),y,max(y)]
   mostr = ['JAN','FEB','MAR','APR','MAY','JUN',$
	[A'JUL','AUG','SEP','OCT','NOV','DEC']
   lat = 50.5 lon = seqa(-180,30,12)
   latstr = ['55','60','65','70','75','80','85']
   lev = seqa(-400,50,19)
   for iyr=0,25 do begin
      yrstr = '19'+strtrim(iyr+64,2)
      m1 = fltarr(13,15)
      m1(0,0) = matrix1(iyr*12:iyr*12+11,*)
      m1(12,*) = m1(0,*)
      m2 = make_array(15,17,/float,value=min(m1))
      m2(1,1) = m1
      map_set,/stere,90,-180,lim=[50,-180,85,180]
      xyouts,.5,.98,/norm,align=.5,'F!IWALL!N ('+yrstr+') -Wm!E-2!N',chars=1.3
      contour,m2,xx,yy,/follow,lev=lev,/overplot,path='path.dat'

      contour,m1,x,y,/follow,lev=lev,/overplot

I am trying to incorporate IDL (v3.0.0) graphics written on my workstation
into Microsoft Word documents. Currently I can either write EPS files, which
I cannot edit on my PC, or 8-bit TIFF files (using the TIFF_WRITE library
procedure) which are big and clumsy, but which I can edit in Word. Is there
a better way to do tis? Ideally, for line drawings, I would write a single
bit TIFF file (if that exists?) and put that into Word. I could then edit it
and place arrows, labels, etc wherever and in whatever font I want.

David Stern of RSI told us a few months ago that IDL for MacIntoshes was under
development, and that it should be released by late 1993.  I've since heard
second-hand that it is about to go into alpha test, so it may be ahead of
schedule.  I believe that the holdup was that some improvements needed to be
made to MacOS in the area of virtual memory before IDL could be ported to it.

Here's to platform independence!

Amen, brother.  We are writing data analysis code which is
currently ~5000 lines with LOTS os subroutines.  There are
some routines that contain 10 lines or more of common blocks!
Global variables would greatly reduce at least this aspect of 
the code.

Also, it would be nice if one could call subroutines from 
other directories.  For example, if a branch of the program
deals with data retreival (off the 8mm tape), I would like
to place all of the routines dealing with this in a sub-directory
named ./Get_Data.  This would allow me to clean up the one
directory holding everything now without fiddling with the
search paths.

Having said this, we are not about to switch over to Solaris 2.1
until PV-Wave runs on it.. we would be lost without PV-Wave!

OK. Using PVwave, I'm having difficulty creating
a pattern-filled contour plot in a Postscript
format.  I've created such a contour plot
on my X terminal, but when I switch my output
device to postscript, all my contours are filled
with blackness.  Here's a sample of one
of my attempts.

PRO test
openr,1,"x.dat" 
openr,2,"z.dat"
openr,5,"phi0af_x"
arr1=fltarr(32,32)
x=fltarr(32)
z=fltarr(32)
readf,1,x
readf,2,z
readf,5,arr1
close,1
close,2
close,5
loadct,0
pat1 = bytarr(3,3)
pat2 = bytarr(3,3)
pat1(1,*) = 255 
pat1(*,1) = 255 
for i =0,2 do pat2(i,i) = 255
pat3d = bytarr(3,3,2)
pat3d(*,*,0) = pat1
pat3d(*,*,1) = pat2
contour, arr1,x,z, /spline, c_labels=0, $
        nlevels = 6, xrange=[-10, 10], yrange=[-2,2], $
        path_filename = 'cpaths.dat', $
        Ytitle = 'z (fm)', Xtitle = 'x (fm)', $
        Charsize=1.75, Charthick=1.75, Font=-1
polycontour, 'cpaths.dat', pattern=pat3d
contour, arr1,x,z, /spline, c_labels=0, $
        nlevels = 6, xrange=[-10, 10], yrange=[-2,2], $
        /noerase, $
        Ytitle = 'z (fm)', Xtitle = 'x (fm)', $
        Charsize=1.75, Charthick=1.75, Font=-1
set_plot, 'ps'
device, xsize=8.0, ysize = 7.0,xoffset=0.0,yoffset=1.5, $
       /Inches, Filename='phi0af_x.ps', /Palatino, /Bold, $
       /Color
contour, arr1,x,z, /spline, c_labels=0, $
       nlevels = 6, xrange=[-10, 10], yrange=[-2,2], $
       path_filename = 'cpaths.dat', $
       Ytitle = 'z (fm)', Xtitle = 'x (fm)', $
       Font=0, Charsize = 2.0
polycontour, 'cpaths.dat', pattern=pat3d
contour, arr1,x,z, /spline, c_labels=0, $
       nlevels = 6, xrange=[-10, 10], yrange=[-2,2], $
       /noerase, $
       Ytitle = 'z (fm)', Xtitle = 'x (fm)', $
       Font=0, Charsize = 2.0
device, /close_file
END; test

Any suggestions?

I get around this problem by simply declaring the common block in an external
text file and adding an include ("@file-name") in each of the calling procedures
Saves a lot of editing if you make a change in one of the commons.

I have seen postings on this net concerning IDL  widgets
but none concerning the PV_WAVE widgets. I was wondering if
anyone out there has tried out WAVE widgets. I am running
PV-WAVE CL 4.01 with widgets. I like the ease of programming
these widgets. Moreover, we can use any of the Motif (or OL)
widgets also apart from the Wave widgets and also mix them.
I donot know if same things hold true for IDL widgets. IDL user?
Only thing I dislike is passing the parametes by common block. 
The program look like FORTRAN programs and I hate the common blocks. 
I was wondering if PV-WAVE can come up with something like a global
declarations. This might ease a bit the parameter passing and
make it easy to add/delete parameters to be passed.

I was wondering if someone out there can summarize the pros and cons
of IDL and WAVE widgets.
