subtract 2 images

hey,

I'm not very experienced with IRAF... I just want to subtract 2 images. It has nothing to do with bias or dark frame subtraction...
To divide 2 images I can use imutil -> imdivide. I look for a similar command to subtract 2 images. Can anyone help me pls??

Thanks!

Milena

See IMARITH. For more complex operations see IMEXPR.
