In PV-Wave DC_WRITE_FREE generates such an error message, when there
is an undefined variable in the parameters. Are you sure, that you
assigned any value to rtar? Can you include the statement "info,rtar"
before calling DC_WRITE_FREE to see if it is defined or undefined?
HTH, Heinz

Whoops! I meant PV-Wave, of course, not IDL. And,
also, my remarks assume DC_WRITE_FREE and DC_WRITE_FIXED
are functions, as you have called them here, and not
procedures, which would also cause an error message
like this.
Cheers,
David

I don't know if this is a "silly" mistake, but it
is certainly not an uncommon one. The directory that
contains these two functions is simply not on your
IDL path. (You can print the directories on your
IDL path to confirm this for yourself.)
I think if you add the directory to your IDL path,
and restart IDL, you will find that things work
a LOT better. :-)
Cheers,
David

Heinz, My mistake was along the lines of what you said, in the end
rtar was undefined. So that problem fixed. Now when I try to format
the file, I get this error message:
% Internal error: Attempt to store into Temp variable with dynamic
allocation..
% Execution halted at COMPARE_TARGET_OFFSET2 <C:\wave_bin\pvpro
\elam_pro/compare_target_offset2.pro( 80)> (DC_WRITE_FREE).
% Called from $MAIN$ .
Right after the loop finishes its first iteration. This is the code:
loop4:
artar=fltarr(nfiles)
axc=fltarr(nfiles)
ayc=fltarr(nfiles)
for i=0, nfiles-1 do begin
spherecenter,aimg(*,*,1),rtar,xc,yc,1,1
artar(i)=rtar
axc(i)=xc
ayc(i)=yc
status= DC_WRITE_FREE('C:\Cryo\SphereCenterData
\referencetargetdata.txt',fnames(i),artar(i),/Column, $
Dt_Template=[1], Format="(A10, 1X, F4.2)")
endfor
fnames(i): String=Array(5)
artar(i):Float=Array(5)
Thanks!
