Hi,
I need to read and set a seris of image processing flags which are
packed into byte size variables. Except the ISHIFT, I could not find
any other bitwise operators in IDL language.
OK, I can always call C or FORTRAN routines from IDL to accomplish this
task. But, is there a simplier way to read set bits in IDL ? After all,
IDL is built on C, isn't it?
Thanks
