Clearly,
logicals are stored in whole words, rather than bits.
Is this general for compilers, or is it an Intel thing?
The language standard requires the storage unit for the default
logical, integer, and real to be the same size. However, there may
be other KIND values for logical variables that may be closer to
what you want. I don't know of any compiler that supports a one-bit
KIND, but some compilers do support one-byte KINDS for logicals and
integers.
