$UDBL
variable
is the identifier of a simple variable, array, simple pointer, structure, structure data
item, or structure pointer.
$TYPE returns an INT value that has a meaning as follows:
For a structure pointer, $TYPE returns the value 8, regardless of whether the structure
pointer points to a structure or to a substructure.
You can use $TYPE in LITERAL expressions and global initializations, because
$TYPE always returns a constant value.
$UDBL
$UDBL converts an unsigned INT value to an INT(32) value.
int-expression
is an unsigned INT expression.
$UDBL places the INT value in the low-order 16 bits of an INT(32) variable and sets
the high-order 16 bits to 0.
