reclass in ENVI or IDL [message #30543]

Hi,
Forgive the second posting as the first appeared to have been lost. I
need to reclass a single band scene to a binary image to use as a mask
on a Landsat TM scene. I'm not seeing widgets in ENVI that enable
user-defined reclassification of pixels; however, it appears that
using Band Math widget along with a custom function that I could
accomplish the task.

The reclass function requires very simple decision criteria. For
every pixel in the image < .15 assign it a 1, else it receives a 0.
Any suggestions or snippets would be helpful to this pilgrim in the
IDL world.
Cheers,

John
