Bitwise Operations in Ada

Bitwise Operations in Ada

Is there a tutorial somewhere that explains on which datatypes bitwise
operations can be used? I don't know why Lady Ada thinks that I cannot
bitwise OR two Standard.Integer...
$ gnatmake test.adb
gcc -c test.adb
test.adb:50:77: there is no applicable operator "Or" for type
"Standard.Integer"
gnatmake: "test.adb" compilation error
Really? I excused the compiler for not being able to AND/OR enumerated
data types. I excused the compiler for not being able to perform bitwise
operations on Character type. I excused the compiler for not being able to
convert from Unsigned_8 to Character in what I thought was the obvious
way. But this is inexcusable.
