Mirko Vukovic asked me to forward this to the group:
-----
I find Hungarian very usefull in designating the ``role'' of variables.
That is one level higher than type. Consider the foolwing
multiple-usage of File and FileName. The hungarian notation allows (me)
a simple naming convention.
vFileName=['file.1','file.2','file.3'...]
cFile=n_elements(vFileName)
for iFile=0,cFile-1 do begin
FileName=vFileName[iFile]
...
In the above, c stands for count, i for index, v for vector. I even use
it in combinations, such as
viGoodPixel=where(mPixel eq ...,cGoodPixel)
Now, vi is a vector of pixels, and cGoodPixel is the count of good
pixels. And so it goes.
