Get the most significant (highest) byte of the word or long value

(so for a long value, msb($11223344) is $11, not $33. To grab the bank byte of a long variable, you need to do this:
|

``lsb(msw(longvariable))`` or the equivalent ``@(&longvariable+2)``.)

:index:`lmh` (x)
|
||||
Get the three low, mid and high (bank) bytes of the given long value. The upper byte (bits 24-31) of the long value is not considered.
|
||||
So this means lmh($11223344) returns the three bytes $44, $33, $22 in that order.
|

For the Commander X16 a possible use of this function is to set the 24-bits Vera address in one assignment statement:

``cx16.VERA_ADDR_L, cx16.VERA_ADDR_M, cx16.VERA_ADDR_H = lmh(address)``

- struct/ptr: really fixing the pointer dereferencing issues (cursed hybrid beween IdentifierReference, PtrDereferece and PtrIndexedDereference) may require getting rid of scoped identifiers altogether and treat '.' as a "scope or pointer following operator"
|
||||
- struct/ptr: (later, nasty parser problem:) support chaining pointer dereference on function calls that return a pointer. (type checking now fails on stuff like func().field and func().next.field)
|
||||
- should we have a SourceStorageKind.POINTER? (there is one for TargetStorageKind...)
|
||||
- add a "tuple" node that allows you to do: a,b,c = 1,2,3 or l,m,h = lmh($00aabbcc) -> l,m,h = $aa,$bb,$cc (can't currently const-fold this, see ConstantFoldingOptimizer)
|
||||
- make memory mapped variables support more constant expressions such as: &uword MyHigh = &mylong1+2 (see github issue #192)
|
||||
- allow memory() to occur in array initializer (maybe needed for 2 dimensional arrays?) i.e. make it a constant (see github issue #192)
|
||||
- allow the value of a memory mapped variable to be address-of another variable, not just a constant number
